died while driving, mechanic stumped

2004 F350, 140,000miles, EGR upgrade, new oil cooler(Puking coolant out the bottle) new turbo (I think i broke it trying to reinstall it) and exhast Y pipes (It were bent???) and new HPOP 5 months ago.

So the other day the truck stranded me in the middle of nowhere. Was running fine, pulling a 4000 lb load. I heard a bump, though it was something from the dirt road. 30 seconds later while accellerating onto the asphault the truck just died. No sputtering or anything. It just shut off. Had it towed 50 miles to the mechanic.

The computer said I have 40psi at the injecters but 700psi at the HPOP.
Dummy plugs installed and rechecked. Same diagnosis.
OK now the problem, everything is tore down to the HPOP but the mechanic still has not found the suspected leak between the HPOP and the injectors.

Any ideas or suggestions? This truck has cost me almost 6000 in the last 6 months. Its getting frustrating.

stand pipes? I've seen the o-rings cut on the older style 04 standpipes before

Please clarify is the 40 psi fuel pressure or oil.
How exactly did they measure pressure at the injectors? No scanner can read oil pressure other than overall system pressure. A mechanical test?

What else did they test for?

Did you also change the IPR valve when you did the work? Same thing happened to mine year before last, I had pressure at the pump but no fuel at the injectors, IPR valve had failed.

An update-
The mechanic is a retired Ford 6.0Ldiesel mechanic. Hooked it up to a Ford diagnostic program. Y'All will have to cut me some slack. I'm new to diesels and some of the Abbreviations are still elluding me.
While cranking the engine the HPOP was putting out only 700psi but somewhere downstream at or near the injectors only 40 psi. I assumed he could measure it somehow.

Anyway after a top teardown the Injector pressure regulator had a hole in the screen blocking it in the open? position. Anyway new IPR, a handfull of benjamins and some beer and its fixed.

not good. How did that hole in the IPR screen get there? where did the debris come from? if you just threw an IPR at it and the HPOP is failing (known on 03-04s) then you're going to eventually trash the new IPR.

Any time an IPR screen is damaged you have to wonder what damaged it and where did it come from
