injector pump

[glenn]

I have a JD 350 Crawler Loader and my question is,
1) As long as I have the throttle lever in the wide open position my dozer will start, run and operate like a new one
2) I can lower the engine to and idle and it will run O.K.
3)but when I cut the engine off it will not start back. Unless I've idle it back up and then cut it off.
4) it has done this two times and now I can't get it started!
