While driving at 65 MPH the engine cut out. Could be the crankshaft position sensor. The truck is a 2500 with an 8.1l engine. Similar issues that the 2001 was recalled for. Same engine and cps as the 2001 but not included in the original recall. This has happened several times at various speeds.

Crank position sensor failure - stall
The office of defects investigation (odi) opened a preliminary evaluation (pe06-016) on may 4, 2006 based on eleven vehicle owner questionnaires (voqs) and early warning (ewr) data alleging sudden engine shutdown while driving as a result of crank position sensor failures in my 2001-2002 general motors c/k platform vehicles equipped with 8.1l engines.in response to an information request letter sent by odi, general motors (gm) provided owner complaint information, field reports and warranty claim data based on a population of 108,338 vehicles. The data was categorized by engine stalls while driving, engine stalls with an unknown driving condition, no start conditions and claims where it was indeterminate if an engine stall occurred while driving.general motor's response included 1,213 owner complaints and field reports of which 289 were categorized as engine stalls while driving allegedly caused by crank position sensor failures. General motors also submitted warranty claims from its regular warranty (5 years/50,000 miles) and from its extended warranty database. From the regular warranty database there were 3,140 claims of crank position sensor replacement of which 147 claims were from consumers alleging engine stall while driving.gm stated that 2,841 of the claims were indeterminate if an engine stall occurred while driving.from its extended warranty database, gm submitted 1,561 claims of crank position sensor failure that it also stated were indeterminate as to whether an engine stall occurred while driving.in total, gm reports 4,701 claims of crank position sensor failure combining regular warranty and extended warranty.similar to gm's statistical analysis, odi's analysis showed that the failure rate for warranty claims of engine stall while driving at three years in service is low (less than 1%).however, further analysis determined that the my 2001 vehicle build period from may 2000 through october 2000 had significantly higher (more than four times) crank position failure rates in both consumer complaint data and warranty claim data than in the build period from november 2000 through july 2001.adding the claims of known engine stall while driving and claims where engine stall was indeterminate, the failure rate at three years in service for this population is over 6%.an engineering analysis (ea06-016) has been opened to further assess the frequency and potential safety consequences associated with the alleged defect in vehicles built from may 2000 through october 2000.

What 2002 Chevrolet Avalanche owners say
Most recent owner complaints, unedited.
The engine will die at any time with out warning. This happens fairly often. Sometimes after trying to restart it will restart with no delay and other times it will take a few minutes. Then it will run normally for no specific amount of time. Then it will die again. Incidences may occur hundreds of miles in between. The dealer says they don't know why it would do this and it would be very difficult to diagnose the problem because it happens spontaneously and it usually restarts quickly. This is very dangerous and turning the vehicle to get off the road when the engine dies is very hard to do.
Exhaust leak in the engine found manifold bolts were broke.
Tl* the contact owns a 2002 chevrolet avalanche. While driving 65 MPH, the contact stated that the engine would stall at any time and the failure occurred more frequently on bridges. Neither the dealer, nor manufacturer were notified of the failure. The vehicle was not repaired. The failure and current mileages were 101,000.
Truck shuts off while driving. When this happens I lose power steering and brakes. Will occur at all speeds including 70 MPH on the interstate. Very scarey situation that could cause a large accident in rush hour. After researching this on the internet, I have found this is a problem with the make and model truck I have. The problem is the crankshaft position sensor. This should be recalled and fixed at chevrolet's expense!
Chevrolet avalanche 2500-year 2002:engine cut off while driving-crank position sensor defect (cps). This seemed to happen almost exclusively after the truck has been sitting for at least a few hours. It started up instantly and normally, then, as driving down the road between 2 and 5 minutes after startup the battery light popped on and the engine was dead. This phenomenon was not totally repeatable - sometimes it will go for a month and not happen, sometimes it will happen 3 times a day for a week. It happened twice the day before yesterday and not all yesterday.
Engine stalled frequently at any speed without noticed. All power steering and power brakes fail when engine stalls, creating a very serious and dangerous emergency situation. Determined to be failed crankshaft position sensor, original sensor has now been replaced by modified new sensor which was put in service in mid model year 2002. Ask gm as to why recall was not put in to place to replace all previous known defective crank shaft position. Why was the crankshaft position sensor modified and replaced in mid year 2002, if there was such a low incidence of failure. I just experienced a $2,500 repair bill due to gm reluctance to fix a "known" potentially fatal flawed part. Thank god my wife doesn't drive my truck, she wouldn't be able to steer or brake the truck to a stop.
Dt*: the contact stated while driving 35 MPH, the vehicle stalled. After pulling over the side of the road, the vehicle was put in idle and the contact attempted to restart the engine but it would not start. There were no warning signals prior to the incident. The contact was told by a friend that they experienced the same problem with their vehicle which was the same make and model. The problem was caused because the camshaft sensor in the ignition malfunctioned. Neither the service dealer nor the manufacturer were contacted.
I recently purchased a used 2002 chevrolet avalanche 2500hd 4x4 with a 8.1 litre engine. The vehicle has approximately 51,000 miles on it. The first problem I noticed was that the engine would crank, but it would not start immediately. The next problem I experienced was that the engine shut off while I was driving it. This resulted in loss of power steering and power brakes, but more importantly, I was not able to maintain the posted 55 MPH limit, and I had to dodge traffic while trying to steer my "dead" vehicle onto the shoulder. The vehicle did restart and I was able to resume as before. This has happened to me at least 4 times. Thus far after 3 trips to the dealer, they have not been able to repeat, diagnose, or repair this problem.
Vehicle began stalling during idle, then stalled while traveling at 50 MPH. Engine shuts off without warning. After researching on the chevyavalanchefanclub.com web site - I found information that others had the same problem. I asked my mechanic to replace the crankshaft position sensor and I have had no problems since.
