Does it take a while to start after it dies?

What is the idle rpm set at... Does it just run at any rpm and die or does it die when you return to idle setting. Maybe its too low of an idle setting... Where did you get the pump and injectors from. Is the pump a fresh rebuild or is it just a differant pump off something else you had connections to....

Timing could be way off, i had a pump once that had problems, and i had to turn the idle way up on it, and advance the timing to make the engine run right, but it always had a lope if you were at low rpm and under a load, a week later the govenor assembly came apart inside it

Is this every time under all conditions, or just after it has sat for a while?

Well guys I finally figured out what the problem was thanks so much for all your help! I found out that the return line where it connects to the fuel selector switch . The valve is not opening to let the fuel to go back into the tank so it was killing it ! Thanks again guys I really appreciate all your help!
