Possibly fuel shutoff solenoid.
They get weak over time and back pressure will keep them from opening until pressure is relieved. (over time/cool down)
I had a CAT that would do it on a Boom Truck. If I came in from a run and shut it off it would not start after a short time.
If I loosened a fuel line and the pressure then it would start right up.
I was too poor at the time to buy the solenoid so I would just shut it off, then turn the key back on to keep the solenoid open so it would restart.
