I have a 2013 Mahindra tractor that runs for a few minutes, then loses power. Throttle response is not there as well. The tractor has less than 14 hr now. I have blown out the fuel system to before the injectors. I loosened up the injector "nuts" and cranked the engine over to purge. I blew into the fuel tank, using my hand as a seal, while the tractor was running, and it increased the rpms for a short time, then reverted back to slow idle.

I did replace the fuel filter as an initial fix, thinking that there was water. Nothing seems to correct the problem. The fuel tank has a built in filter, so it wouldn't seem that it would be solids contamination. I see no evidence of jelling.

Any ideas?
