Engine Stall problems of the 2002 GMC Envoy

2002 GMC Envoy slt. Engine stalls at highway speeds. Loss of power brakes and steering. Engine will not restart for anywhere from 20 to 30 minutes. This is the 5th time that this has happened to me in the past 4 years. 4 times on the freeway and once on a surface road. This time I was with my wife and 11 month old daughter. I was not able to pull the car over to a safe location. I ended up in the left shoulder in next to the fast lane with only about a foot of space to my right where the cars were whizzing by. I cannot tell you the terror that I felt, as my daughter was in her child car seat on that side as the cars passed honking. This vehicle is very unsafe. I have read many internet postings and it appears that this problem occurs often with this make and model, yet whenever I take the vehicle to the dealership all I get no codes are displayed, we cant duplicate the problem, or they start throwing parts at it. So far I have replaced a fuel pump and a crank angle sensor, had the fuel injectors cleaned. The problem persists. I want to make sure that my description is clear. The engine temperature is normal, voltage is normal, outside temperature can be hot, warm or cold, it can be day or night. It has happened in all of these conditions. What is worse is that I cannot restart the engine for around 20-30 minutes, presumably there is some sort of reset on the computer ecm/pcm that occurs that grants me the right to now drive my vehicle again? this is unacceptable. My daughter, my wife or I could have been injured or even killed. I have never complained about this before except to the dealer but now that I have a baby, I am livid. I am a very experienced driver and have always been able to pull the vehicle to safety even without the power assisted brakes or steering. I very much worry about less experienced drivers such as my wife who is from a foreign country and has only been driving for two years. If she had been driving we would have.

Driving on the interstate at 70 miles per hour, without warning the engine stalled. No crank and the car would not restart. Panel lights operational, abs and emergency brake warning lights illuminated. Car is currently at dealership awaiting repairs.

While waiting to proceed in traffic with foot on brake and car in drive, engine suddenly stalled out and was unable to be restarted. Also, driverside mirror keeps resetting when unlocking the automatic doors. Wipers don't function properly when in intermittent mode. Car is at dealer now, hopefully they can resolve this. Vehicle is equipped with rainsense automatic rain sensing wipers. Rainsense works only when in intermittent mode. Settings adjust sensitivity of wipers but not frequency. Wiper fails to make a complete smooth pass across windshield. They stop several times during their sweep and stutter. After a few second pause they resume their sweep. Wipers work fine when set to standard high or low wiper settings.

Engine stalls, causing consumer to wait a half an hour to start vehicle again. This has happened three times. Dealer has inspected vehicle and could not duplicate or correct the problem. Please provide further information. Also, abs failure.

2002 GMC Envoy engine stalls while stopped at traffic light. Sometimes a near-stall condition occurs whereby the engine idle dips really low, engine shudders, then idle recovers. This usually happens just before or after the air compressor for the rear suspension inflates. So far the pcm, throttle body, and ignition switch have been replaced. Dealer is currently making 4th attempt to fix problem. Problem has been occurring since 8/2002.
