engine problems

i dont know what im doing never been to this place but i need some help. i got a 92 F-250 7.3L banks turbo charged and any time it gets a load like when i turn the wheel all the way to the left or right the engine will die at start up it will fire then it will just die and while i am driving and i let off the throttle it will die...i thought it might of been water in the fuel but im thinking something might be clogged or i need new injectors but i have no clue and im getting ready to say screw and give it back to my parents and let them deal with it

Moved your post might see more action here. First off to Powerstroke.org. When is the last time you changed the fuel filter?

you can bump the idle up on this truck, but more than likely you have a injection pump acting up, run a fuel pressure test just to make sure you dont have any base fuel pressure issues

What is the base idle RPM? It should say on the engine or door frame on a sticker what the idle RPM should be. I believe my 94 F-350 IDI diesel is 550 +/- 100 RPM's. Maybe it's just too low...
