7.3, no start when hot: need clever ideas

Starts up fine after cooling for 1-2 hours or if you kill it and start again immediately. If it sits for 30min or so it will crank like mad but never start.
Thanks for any help.

No Ideas?
Died on me today in traffic and wouldn't restart, which is a new and negative development.

Truck is parked now. Died again, and would not restart. Once hot it will die and not start from significant deceleration as in coming to a stop.
No ideas?

Mine did the same thing and turned out being the IPR. Replaced it and have not had any more problems.

IPR 0-rings are bad, replace them or the whole IPR and you problem should be fixed.

Thanks, that is what I was thinking, will I get any codes? I have been meaning to scan it. I switched in a * 17 hpop and it had the ipr on it, only about 2-3K miles ago.
If the o-rings are bad can i tell by oil on the outside of the sensor?
Thanks

No codes. Just pull the IPR and look at the o-rings on the end, I would just go ahead and get replacements before you do the job because if nothing else they need done anyway.

Put on the ipr solenoid from my original hpop. Test drove till hot, died and would not start. Towed it home, put on the whole ipr from the original hpop. Still won't start, last time it had to cool for six or seven hours. Hooked up the super chips scanner and got 02-p0113 high air intake temperature (tymar style intake and I removed the sensor that was in the air box???)
01-p0340 cam sensor
cleared codes
I reset the truck to stock, still wouldn't start.
So do I still buy an ipr??? Or is it something else?
Thanks for help.

The o-rings on the ipr looked ok.

Looks like it was the cps, so far runs well with a new one.
