Suspected defective ignition switch and/or ignition switch passlock security on or about jan 17 2014 I was traveling about 30 MPH when the engine stalled with loss of power steering and brakes. I was able to stop without incident. After 10-15 minutes I was able to restart the vehicle and drive as normal. For several years after driving the ignition key was warm or hot when removed from the switch. In early 2013 the engine would occasionally stall immediately after starting but would restart after waiting 5 to 10 minutes. On jan 14 when at a gas station the engine stalled but I was able to move the car to the curb. After 10-15 minutes I was able to restart and drive normal. * passlock ignition security feature is widely reported to be a cause of these symptoms.

What owners say
Bought from new 99 tahoe. Has had 2 runaway over speed events. The 2nd was yesterday. It has been having also, loss of power at time when first starting off. It goes away quickly, usually in few seconds. Hear at least one exhaust popping noise during event. Never looses power during long highway travel. Both times the runaway acceleration was after a hard acceleration. Goes into bauck ( loss of power) & then into full acceleration! Last runaway required 3 key off shutdowns to relieve. Neutral caused it to rev to 5000 RPM. Brakes seem to control run away a bit at 40mph, but not down hill! We never use cruise control & it was in off position. Hard to steer of course with engine off at 40+ MPH! Suspect fuel injection system. Was in drive position at occurrence. First occurrence was about a month previous. It was controlled by full braking stop then. It was then only at slow speed to start. A less experienced driver on the steep hill I came up on during run away could have been killed into trees on side of hill. Ex nasa engr with only carburetor knowledge!
