Need some help!!!

I have a 2004 f250 cc 4x4. Over the last few weeks it has been losing Power. It build boost up to 26psi but the truck goes no where. It's acts like it not getting fuel.
I'm using the sct sf3 with idp extreme street. Stock exhaust with no muffler or cat. Egr delete.
It does have a oil leak at the rear of the motor but I'm not sure where from. I changed the fuel filters and it didn't help any.
The truck seems to run fine as long as I don't get on it hard. Starts right up cold or hot. If it's below 30 it idles ruff for a few seconds.
What could make it do this? I don't have a way to check the fuel pressure so I was thinking about replacing the fpr spring with the new ford one to see if it helped.
My turbo cycles the vains so I don't think it's that.
Is there a way to pressure test the hpop system? If so could some one tell me how or a post that will. Thanks for the help.
I returned the truck to a stock tune and still had a loss of power.

Don't think its the hpop. Mine is at the dealer now for the same reason, they have installed a new hpop and replaced injectors. Nothing they have done has fixed it. They are having a ford engineer out tomorrow to help figure it out. I will post something to you when they find out what it is. Truck been in shop for 2 weeks with this problem!

[bbtranport]

Not yet!!!! Trying t get someone to return my call this morning. As of last night they wanted to replace PCM. Thats the last I heard from them. Will let you know what happens

[bbtranport]

Well they replaced pcm took truck for test drive and had to tow it pack in. BACK TO THE DRAWING BOARD!!

Wow sorry to hear that. I think mine is the hpop system. I took the truck to a friends house and shut the truck off. Tried to restart it about 20 mins later. Took about 30 seconds of cranking to get it to start. When I got home I shut it down and tried to restart it. It did not start up again till I let it sit for a few hours.
Hope you get yours fixed soon!!!
