This is the first time i have had this happen, i started my truck today and i heard what sounded like the starter stayed engaged with the flywheel and i turned the key off and the truck stayed running, so i popped the hood and was going to pull down on the fuel shut off, just as i got the hood up it shut off. I restarted the truck and it is fine now, what do i need to check out? Any info would be very helpful.
