03 died and no start

[TimeEater]

Ok to start with its a 2003 F250 with the 6.0, has 118k on it. It has been a good truck till the last few months.
It started when it was still kinda chilly in the mornings, I went out to start and warm up the truck and it started and shut back off, tried it again and same thing, third time stayed running and all was good the rest of the day. Plugged it in that night and same thing next day. I park on an uphill and after looking around on the net some one said to try parking downhill and I did. Started up just fine after that, just needed to warm up to run strong.
About two months ago I changed the oil ( 15w-40 with ford filters) and noticed oil leaking down the bell housing, up till then haven't noticed any oil leaks. About a week later a good size puddle under the truck. Turns out to be the ICP and I replace it, but not pigtail, tried to be cheap and squirt it out with electrical cleaner. Changed the Oil again to 5w-40 Rotella
Up til 2 weeks ago truck would start no problems downhill and a warm up, until one day I was in a hurry and started it up and didnt let it warm up and started down the road, got less the a mile and it just shut off.
The only code was the p2285 low ICP. Since then I have checked all fuses, replaced IPR ( nothing in screen but indented), did the ICP pigtail. Scanguage II says ICP around 200 but bounces up to 350 and drops to like 180. FICM is 48V key on and 47.7V cranking.
There is oil that is leaving the turbo into the CAC tubes and starting to soak them.
I have checked that there is oil entering the oil filter housing and the oil does register oil on the dash but it takes a few seconds of cranking.
Any insight would be greatly appreciated.

I went through this same thing not to long ago. Same codes and all. Turned out it was my FICM. Volts read good on it but the boards inside were fried! First try checking the conectors on the back of the FICM. You could have wiggled something loose when you were changing the ICP pig tail.

How did you find out FICM was bad? Did you just replace it or resolder it? I have rechecked the harness and it all seems good. As far as the CAC tubes being soaked it on the outside and there is quit a bit of oil under the turbo that wasn't there when I did the egr cooler hose last year. Is that a sign of something? Also unplugged the ICP and on SGII showing 1500 psi.

It was HPOP that was bad, replaced and is running.
