Recently my JD350C diesel runs fine for about 15 minutes and then over about a minute loses power and eventually stops. During this power loss it doesn't respond to increasing throttle. It will start right up but within about 30 seconds will stop running. If I wait about 20 minutes it will start fine and run anothert 15-20 minutes before stopping again. This same pattern can be repeated over and over. This is no problem if you want to work for 15 minutes and then rest for 15 minutes, over and over.
I cleaned out the fuel tank and replaced the filter in the tank. I also replaced the fuel filter itself which was clean. When I disconnect the fuel line at the injector pump it gushes when the engine is started, which I guess indicates the regular fuel pump is working fine. I have never done anything to the fuel injection pump or injectors. It sounds almost like a vapor lock to me but I don't know what would cause this or how to fix it (and I could be totally wrong).
I would also add two other points which I don't know have any relevance. The first is that before my tank cleaning, for years there has been a large amount of suction when the fuel cap is released. That seems to be gone now. The second is that the fuel shutoff solenoid has pretty much always been dysfunctional but I don't know if this is related.
Any help would be appreciated. I've got lots of dirt waiting to be pushed around. Thanks, Jerry
