shuts off when warm

thanks in advance guys
2006 f250 king ranch 6.0 psd

3 weeks ago i was driving on 95 70mph and noticed a loss of power
i had to drive about 6 miles to pull over. just when i got to the shoulder
the truck shut off..oil in the coolant so oil cooler blown

towed to the dealer they said oil cooler and my extended waranty gave me the finger so i took it home to do the egr delete and oil cooler . funny thing is the truck started right up to move it into the garage

so i did the cooler and egr, got some trash in the system so ended up replacing the hpop and ipr valve (screen was cloged with shop rag lint)

however still takes awhile to start then shuts off after about 30 mins

so i then removed valve covers and did stand pipes and dummy plugs on both sides also had just passenger side injectors checked (had to replace 2 of them) did not have drivers checked (dont ask)

when truck starts cold (verus scan tool) icp is 800-900
ipr %is around 35%
as it warms ipr goes to 85 and icp begins to drop

i did the air test with covers off and air seems to be coming out the injector
tops. even on the side with the new and checked injectors once i put the new injectors i then could hear the same air noise on the driver side
(i guess i couldnt hear the noise before because too much air was coming out
on the passenger?

the oil rails nipples seem ok tight and not scored or anything i just dont know what to replace and this truck is killing me

i was wondering if mabye i got the oil pretty darn hot from driving the 6 miles
and mabye the oil rail could have cracked ? looks ok though i just cant test them

When you replaced the HPOP, did you install the updated STC fitting or use the old one?

ficm voltage is 48.5

the verus scanner shows the icp pressure going down to about 430 before the truck shuts off
ipr 85% after warm

Then just replace the ICP sensor, it's on the passenger valve cover... unless you did already...

You have a HPO leak. Pull the valve covers and replace the standpipes and dummy plugs.

It's worth a try, but you are correct; it's usually a no start condition item.
