Trucks shuts off while driving

I have a 2000 dodge ram. I had the same problem the truck would just stall no matter how fast or slow i was going. It ended up being the crankshaft position sensor. You need to check for codes to find the problem. p0385-p0389 is the crank shaft sensor. It takes about 5 min. to change if thats the problem. On that year you might be able to turn the key to the on position but not starting then off, then on, then off, then on (three times) on the third time leave on and watch the odometer it will flash codes then will say p-done.

I had the same problem at about 150,000 miles the ECM develops problems and will shut off the engine, gauges go dead. Restarts after cooling down some. When it dies check quickly in the led odometer/tripometer if it says No Buss for a few seconds it is probably the ECM. They can be ordered online for about $250 delivered.
