Last year I bought a used 2002 F-250 diesel. It is in great shape with 78,000 miles. At least five times in the last six months since I got it, it has shut down while I was driving it down the road. I lose acceleration, then a few seconds later the engine stops. Check engine, water in fuel, check gauge, and battery lights all come on, but go off as soon as the engine is started again. Gauges are all normal before and after it turns off.
They told me that if I stopped, put it in park, turned the key one click back, kicked the PCM, and tried to start it again they would be able to get codes to determine the problem, but the engine light doesn't stay on long enough to store a code. They have let it run at the dealership, but haven't been able to replicate the problem so they are thinking that because it will start after I kick the PCM that is the problem.
But before I spend $1000 a new PCM that MIGHT fix the problem, I wanted to see if anyone has any other theories.
