89 3.0 pickup would occasionally cut out and die usually give it a minute or two and it would start back up. Started to notice that on a bumpy dirt road it was cutting out worse. While it was running I wiggled the fuse box and it would die but then start right back up. It cut out one final time and won't start up. Any ideas or where should I start?

 

Looks like you answered your own question of where to start. Throw a meter or test light on the hot side of the fuse terminals and wiggle starting with the EFI fuse slot with the key on
