IPR nut still on?
ICP sensor in good shape?

Could also be the cps

Classic CPS symptoms.

Mine didn't give me any symptoms, except it wouldn't restart....

You had one of those "*** YOU" CPS's.

I agree with CPS as a first place to start. They are only about $25 from your local Ford dealership, and you should always carry a spare anyway if it turns out not to be the problem.

Change the CPS again they go out out of no where some times.

OK I'll try a new one thanks

'03 was 12 years ago, long time for a CPS.

Leaking fitting on HPOP is o-rings.

Happens eventually on all of my current and previous 7.3's definitely CPS-imo
Usually pop it in neutral refire drop it in drive and keep rolling until I have the time for a swap and fixes it every truck every time
