Stalling problem

[FL_SmokinPSD]

Hey guys, ive been having nothing but issues with this truck so far, Truck was idleing like crap and getting bad MPG, tracked it down to a ICP, replaced it and ran great......for a day.

Then i was beating on it a lil and 5min later it died, wouldnt re-start, had a lil less than 1/8th tank. i took off fuel cap bowl was low and pump was pumping only pumping bubbles, added more fuel and it started but is was running rough. If i hold the throttle at 1500rpm its surges a lil. Then yesterday i got back from a road trip, got off highway and it stalls, starts right back up and stalls ant next light, does it every time im driving and i get off the throttle.
On the highway it was sluggish and sounded like waste gate was open a lot
And is still only getting 10mpg even on highway

PLZ help can afford this anymore

Its a 2000 f350 7.3 4x4, Dp_tuner, DIY intake, muffler delete.

THANKS

bad fuel.crap in tank and pick up tube may be clogged?change cps,and if you have a chip on it take it out and put a scanner on it to see what kind of codes its got.

New cps from autozone. It was running like crap before i filled up and has been getting worse, and i only buy my fuel from one place and nobody else is having this issue. chip is coming off tomorrow. along with a pressure test.

Whats the fuel pressure supposed to be on this truck?

okay so i found a fuel leak around the cap, fixed it and had ford look at it again, they found a 1211 code but said it was nothing and was caused by my dp_tuner. truck seems to be running better but mpg is still down. any ideas
I just replaced ICP 5 days ago.

The truck is running better: is it still stalling while driving? Has your CPS been replaced? Ford was right about the 1211 code. In a nutshell, it basically means your HPOP is being pushed(i.e.- the DP tuner). You can take that out of the equation.

yep still runs like crap and stalls. it gets worse by the day, takes longer for it to start too
