Here is a good one I have been fighting,
truck shuts off like you turned the key off while driving but wait a few seconds and it starts right back up, but if you try to just start it back upwithout waiting it will just crank. No codes, doesn't crank like it ran out of fuel just starts back up. Could it be a ground? New vp44, App, alternator. Yesterday day on a 300 mile trip it did it more often like something had to cool down. I'm thinking maybe computer?
