1999 Ford F-350 SD: engine stalls while driving

Filed May 9, 2007 · Engine · 52,086 miles · UT

Vehicle began having random stalling or not starting without cranking for a long duration. Finally vehicle stalled in traffic and would not restart. When vehicle stalled a loss of power brakes and power steering was noticed despite the vehicle being a manual transmission and in gear and being back driven as termed by ford motor company. Vehicle required a tow truck to deliver to dealership, where it was determined the cmp sensor was defective. Trouble code p1111 was found by technician. I was told this was a "problematic" part and I should carry a spare in case it happened away from the city. As a result I chose to purchase a spare part and keep it in the glove box for just such a repeat occurrence.

I was driving and my truck stalled before getting to a complete stop. I was about to reach bumper to bumper traffic. Luckily there was grass on the right hand side and I pulled in there to avoid hitting a car. Had to go over the sidewalk. After turning off, I tried to start with no luck. After 10 minutes I tried again and it started. A little down the road same thing happened, it stalled. Happened like 2 more times until I got to work. Called my mechanic and he stated that the cps usually goes out and he bought one for me. Installed it and it worked. Just waiting for the next time it happens as I have read these things give out all the time.

I owned a 99.5 ford f350 with the 7.3l diesel and manual transmission. At around 30k miles, driving down the highway at 65 MPH while towing a loaded trailer, the truck shut off. This left me with no power steering and no power brakes or ABS brakes. Had the incident occurred on a steeper grade or busier time of day, it could have been deadly. After pulling over to the shoulder, the truck restarted and ran briefly before shutting down again. It had to be towed at that point. The truck was still under warranty. After the second attempt at fixing the truck, which LED to another high speed stall with loss of control, they finally replaced the cam position sensor (cps). I had told them that this was probably the problem when I had it towed the first time. It seems common knowledge among ford 7.3l diesel owners that this part fails without warning at as early as 500 miles on the odometer. Most owners carry a spare in their trucks to avoid being stranded. My concern is that this has become a major safety issue with these trucks as more and more families use them as grocery-getters and/or the family wagon. A less experienced driver or a driver in a more hazardous setting would not have fared as well as I did. I urge you to research this problem and bring it to light so that ford can no longer sweep it under the rug until people get hurt. As these trucks get more miles on them the odds increase dramatically that the cps will fail leaving the vehicle in an uncontrollable state in many instances.

The cam position sensor on my '99 ford f-350 w/ 7.3l power stroke is failing intermittently. These failures cause the engine to shut down instantly with no warning. When the engine shuts down there is a loss of power steering and brakes. This has occurred in traffic on interstate 283 in pa causing the vehicle to loss steering and brakes in rush hour traffic with no warning. On one other occasion this occurred in a parking lot causing loss of control of the vehicle while turning due to loss of steering and brakes when the vehicle stalled, causing a minor collision with a curb. No property personal injury occurred. This is a common problem with these vehicles and in my opinion is a very serious safety issue.
