Engine shuts down while driving in afternoon. No warnings, no check engine light. Pull over and restart truck and go. Last time it did this it took 3 tries turn over.

Good afternoon,

This could be tough to track down. There are several possibilities. I doubt it is fuel related as it starts right back up.

It could be an ignition switch which was really common.
