Loses Power and Dies on Highway, No Codes

[RNally]

Had a customer bring me a truck that died on him on the highway. He stated it began losing power and finally died. He waited 15 minutes and started right back up. Drove another hour, and same thing, gradually lost power and died again. Waited 15 minutes, and fired it back up and babied it to my garage. Truck has no codes, starts right up for me. Its an 03 with 150k miles. Any ideas???

High pressure oil leak. Or HPOP

Think it would be a leak though since it starts back up so quickly after shutting down? I was thinking HPOP possibly, but cant get it to act up on me.

Sucks when things don't act up when they usually do lol

If it's not HPO check fuel pressure next.

Just following up, pressure tested the fuel system and the gauge was jumping between 20 and 50 PSI during acceleration. Ended up being a pump going bad.
