Hi, I own a 2004 Kubota M6800 HDC. I'm having an intermittent problem. the tractor stalls after 3 or 4 hours of work. First I thought the fuel filter was plugged and I changed it, it ran fine for a few more hours and the same thing happened. Something I noticed is the fuel sediment bowl level goes down and back up while the tractor is running. Is that normal? There is a small strainer inside the bowl when I take it out and clean it (even though it doesn't look dirty) and bleed the fuel system, the tractor runs fine for 3 to 4 hours and stalls again. I drained the fuel tank and re-filled it with new fuel, the tractor ran fine until about half tank. The problem seems worse when the tank is bellow half for some reason. I'm wondering if its a faulty fuel pump or injector pump. Is it possible that air is getting in the fuel system? Any help would be appreciated. Thank you.
