Been a gm try to have it scan 4 codes if no codes are present check fuel pressure at fuel rail u will need a fuel gage that have a shradder valve connector fuel pressure should be around 30 to 40 psi for port injection or 60 psi for cfi
Fuel Pump or fuel filter will be my first guest. Did you pull any Codes from the truck already?

SOURCE: 99 F250 V10 Sputtering
It takes just one of the coil on Plug units to cause sputtering and severe shaking. Fortunately the prices have dropped slightly for the coil units. The bad news is it is still close to 100 bucks from the Ford dealers. I have had to replace 3 of these on my 1999 F250 superduty V-10 since I bought it new. I believe there may be some compatible aftermarket units out there for high performance V-8 engines, but can not confirm compatibility.
SOURCE: truck is sputtering, especially at low rpm. It is
check the generator to see if it putting out enough volts
SOURCE: Choke Light rough idle
adjust your carb, the 2 screws on each side of the carb adjust so you can get the car to idle correctly, also check your distributor
SOURCE: truck sputters and dies when you put it in drive or reverse.
Most Likely a vacume leak. Check the engine and surrounding engine bay for a loose hose. I would check the mass air sensor, make sure it is free of debries.
