I have a 1999 IH DT466E that will not stay running. It will start right up and then run from anywhere from 30 secs. to several minutes. It then dies, but will start back up and do the same thing. I have replaced the fuel filter on the drivers side, and the high pressure oil pump is also new last fall. This is somewhat intermittent as I was able to drive it home 35 miles with no problem after it initially began dying. If I feather the throttle I can keep it running, but of course not efficiently enough to drive it. When it dies it shuts down quickly. I have went through the wiring and feel confident it is probably a fuel related issue and not electrical, although I am not real knowledgeable with diesels. My only other thought is the ECM? mounted on the drivers side of the engine above the high pressure oil pump. Thanks in advance for any assistance you can give me.
