So I have done some work to my truck and I will get into that in a minute, but now I have an issue with it will start decent cold and runs okay until the ECT and EOT reach about 130 degrees and then it will continue to run but runs rough sounds like a miss, no throttle response, no power in drive when hot, no smoke, and no codes. It has stalled out on me. I have unpligged the icp to no avail, sometimes it will restart other times it won't even with the icp unplugged. Now the kicker is if I rev it up to 2k rpms in park it runs like a beast and all the issues go away. Then it returns to idle and the problems are back. I am at a loss racking my brain here.

What I have done:

So this all started with a cyl 3 contribution code, I fixed that with a new pushrod. I removed all the injectors and cleaned the spool valves and resealed all 8 injectors, did new nipple cups and o rings, new stand pipes and dummy plugs. I have pull the valve covers off and checked my torque for my bolts and stand pipes and dummy plugs. Checked my fuel bowl for bubbles and I have none.
Monitoring everything with the torque pro app, I will attach screenshots and try to explain them, I also have video showing what it's doing.

So the pictures show one revving up to ~2k rpms, one hot idle maybe two, and one right when it gets to running rough.

I would be happy to do more diagnostic stuff but I have the turbo off (just cleaned it up), ipr valve off (had remnants of Dorman gasket on the screen) waiting to get a new screen, ebp valve and tube off just cleaned those out.

Details about the truck:
Its an 04.5
Oil cooler and egr delete from XDP Jan. 2018
New Degas bottle
Blue spring upgrade recently
Found out FICM and driver side bank of injectors were replaced with remans
Turbo is a reman
Rebuilt turbo 2 years ago
Replaced all filters when I bought it with OEM motorcraft and that is all I buy and use
I think that is all

No hot start and running rough is loss of hp oil. Snap to connect or STC fitting on the HPOP i belive is where you will find your leak. There is an updated solid T ORB fitting you can get from Ford

Could also be that you nicked the oil o ring on top of an injector putting the rail back on. Its easy to do. I've done it myself.

Now how big of a leak? Would that even show up down the side of an injector or would the ipr % being ~29% show that?

Now what would cause a stc fitting to break?

Its just a swivel fitting with an o ring. Eventually they all fail.
Thats why Ford sells the updated Fitting. I belive it was factory on the 06 or 07 models
The reason they used a swivel fitting is that the fitting has to be square to the oil passage into the block so it doesn't spit out that o ring.

When you pull the pump and install the new fitting it is imperative you get it square or it will blow out the o ring.

If it is an injector o ring, only that or those injectors that got nicked will have a miss.

If its not been done you cant go wrong changing the stc fitting as it WILL fail at some point

Almost hate buying these things used when you have no idea the history on it whether that work has been done, now if it has whats the likelihood of it breaking again?
