03 350 7.3 engine stops while driving

my truck shuts off like you just turned the key off at all speeds while driving. at highway speed rpms will drop real quick and then come right back up. at low rpms the engine stalls but will start right backup with no problem. i have an electric start and it started right around the same time. not sure if it was before or after the electric start but it is disconnected and is still cutting out. it does not pull any codes and i do have a super chip. any thoughts thanks

Sounds like you have a short in your electric start. I'd go through all the wiring and see what's going on.

have you ever replaced the cam postition sensor on your truck. That maybe going bad. If you disconnected the electric start and it still does it I would check that out.

Sounds like the CPS to me. My truck did the same thing, and it was the cam position sensor.
