So I was driving home last night from work last night and went to accelerate up a hill and it was like you shut the key off on the truck. and now it won't hit a lick. Abouf a month ago I had the turbo rebuilt and motorcraft injectors installed. Truck has been running great since. I have a scan gauge II and these are my numbers. Key on ficm 48-49 - icp 0 - ipr 14.9... and when cranking ficm 48-49 - icp 64 - ipr 85... Any help or info would be appreciated.

Shutting off unexpectedly like that is very much a trick of a failed IPR valve.
I would pull the valve and look it over. You can ohm check it also.
Resistance should be between 3 and 15 ohms (typically around 6 ohms), pull and inspect for mechanical plugging, damage, or stuck open.

That is a part of the reason for suggesting you check the IPR valve ....

Just to give a update on the truck. As stated above I did have new motorcraft injectors put in the teuck about a month ago. Had it towed to the shop and he finally cared me today a d said he had it tore apart a d turns out one of the injectors blew apart. So.ething about a upper o ring I think. On the bright side its all covered under the motorcraft warranty and I won't owe him a dime. Sure is better than a hpop.
