need help bad... the mechanic is stumped....

[excalibur24]

I have a 05 f250 6.0 with 53,000 miles on it... the other day i was on the 4 lane and drive good, all of a sudden it just lost power (but didnt die).. a few days later it died and wouldnt start, so i changed fuel filters and air filter, all not that dirty.. still nothing... i got it started and was running great, got up to normal running temp, and i shut it off and tried to start it back and nothing... it starts cold and dies when it gets warm... the mechanic pulled a few codes and said he fixed it, he drove it all day while i was at work and ran great, i go that evening to get it and i make it 100 feet down the road and it does the same thing, dead... they have done fuel pressure test, its good.. dropped the tank, clean as a babies butt... funny thing is while the fuel test equipment is hooked up it runs great, take it off and i get in it goes ****ty.... please help, i really need help its breaking me up... i am going crazy..

My money is on P2290 and P2291 ICP too low/while cranking are at least one of them. Is this YOUR mechanic or a dealer mechanic? With only 53,000 miles on it, this repair should be covered under warranty unless your warranty in-service date is before Feb. of 2005.

Its not my mechanic, its a mechanic here in texas, i am out of town... warranty ran out in january, i checked....

If you don't mind posting your VIN I can check to see what exactly has been done under warranty.

the truck isnt right here with me at the moment, but if you would please check back with me tomorrow i will have the list of codes and the VIN number... PLEASE this will be very helpful for me.......... thanks....

Yes, I would like this information before posting what I THINK is causing your issue.
