If i let it sit for awhile it will start back up and drive around for halfhour before it starts to stall again.i recently replaced the tps due to code shown, and fuel pump relay.
TRY CHANGING THE FUEL FILTER, ALSO CHECK YOUR RELAYS, MIGHT PAY TO HAVE THE INJECTORS CLEANED & SPRAY SOME GOOD QUALITY CARB CLEANER DOEN THE THROTTLE BODY INTAKE VALVE
Code #34: Mass Air Flow Sensor Low. GET TO A BREAKERS & RIP OF A MAF SENSOR - COUPLE O BUCKS OR FREE IF YA STICK IT IN YA POCKET!
Code #44: Lean Exhaust indication. CHECK YOUR LAMBDA/OXYGEN SENSORS
Code 34- EVP voltage a Code 44- Thermactor air system inoperative-right sidebove closed limit

Like Laurie Mack said. It is the inertia switch below the glove box. Here is some funny information. DON'T change the fuel pump first. Interesting fact: I bought the new inertia switch from Ford and the install instructions that came with it said to install the switch in the protected area to the right where the fuses are. It is like Ford knows it was a dumb place to put the inertia switch, but they won't let you know until after you buy a new one. I have read at least 20 other people on here that had the same problem I just had.

Check out the catalytic converter, might be plugged up. I have seen some cars that will run fine, and like someone threw a switch the car acted like yours, no power, would not rev and died. Later when cold they would be OK for a while then just get worse and worse.

You may have some warranty left. Some DOHC engines have a special problem with Cam Phasers. The throttle position sensor could have been harmed by the jump. Have a dealer run the Vin#.
The electronics could need reeducating. Its possible that the brains could have new variables caused by the jump. It would not necessarily "burn out" the brain but flipped some settings with the extra power.

Usually answered in minutes!
replaced fuel filter forgot to add that. will def look into the cat i thought when they plugged you slowly lost power? inertia switch seems ok but i will look into it too
i should also add that it runs fine sitting in the driveway and always starts right up it only stalls when i take it out and usually around cruising speed (55mph)
i usually run the truck at 14 tank and have heard that puts eccesive strain on the fuel pump im wondering if the pump i installed is burnt out. fuel rail doesnt have a schrader valve so im not sure how to check fuel pressure.
