help, died and won,t start

Help, 2000 7.3 I had driven about 10 miles when truck died like you turned the switch off, would not restart. After towing it home and checking a couple things,(I'm just learning about the PS) several hours it cranked and idled an hour in driveway. I replaced the cps and checked the fuel pressure, 58 psi at wot. Today after 20 miles it quit again and would not crank. No CEL, Wait to start is coming on, turns over good, 60 psi fuel. no codes. I will see in the morning if it cranks cold. also changed fuel filter after it quit the first time and the oil ( Rotella 15W-40) only has 2500 miles on it. Where do I go from here?

Do you have a tuner?

If you do I would make sure it is still seated properly.

Got the truck in my shop, still won't crank,fuel presure still 60psi, unpluged icp still no start. When turning motor over scan tool reads cranking rpm. I'm guessing that means cps is good. hpop is full of oil, checked for loose connections and whiggled plugs to sensors and plug at valve covers. cel is not on but I don't have AE to check it. is my next step to remove and clean ipr or should I go somewhere else?

does the wait to start mean the number 30pcm fuse is still good?
I wouldmaybe unplug the fuel heater, then check the fuel heater/pcm fuse.
I think but am not sure that the wts light means the fuse is good. The heater can be screwing with the electrical current. Try unplugging it and a different fuse, cant hurt

I'm at a point I don't know where to go. I got a cps from international and put it in, and took an idm off of a running truck and tried it and also put my idm on the other truck my idm was good but my truck won't crank with either.So i've eliminated fuses,cps,icp ipr, hpop, fuel pressure in fuel filter stays at 60 lbs,idm is good, checked harness from idm to injectors for short,ground and resistance through injectors, new batteries. Help

I hooked a pressure gauge to each head and with the icp unpluged the pressure in both heads was 1700 psi. Then I plugged the icp back up and the pressure climbed to 3500, dropped back to 2500psi and stabilized.
