I have a 1993 ford L9000 aero max the truck has a repaired computer repaired engine. The turning on and off all started when I hit a big pothole it turned off right after that it happened again. A while after then it started to become more frequent and yesterday it worked all day and didn’t turn off as soon as I filled up and started to head back home; it turned off and never turned back on. It is not battery or the starter, nothing in that nature as to why it didn’t turn back on yesterday. If anyone could help, please let me know before I start wasting an unnecessarily amount of money on it.

Hmm, we don't really work on big trucks like this, but I will try to help. The fact that you it a bump and the problem starts; it sounds like a connection problem like the ignition switch is old and needs to be replaced. Does the truck still have all electrical when the problem is happening? I would also check the engine power cables and grounds.
