'03 No warm restart

I need some help here. Friend has an '03 6.0 with 215,000mi, well maintained. When cold it starts instantly and runs flawlessly, until oil temp reaches 135* or so and you shut it off. ICP during warm crank is 355-375 psi with IPR duty cycle at 85%. Air tested system at top of HPOP, found no leaks. Replaced HPOP and IPR with same results. No codes stored other than an EGR code or two, EGR cooler deleted also. Any help will be greatly appreciated.
