I have a 2003 JD 4510 utility tractor and am having an issue with power loss. When mowing with a 5" BH, after about 30 min, the engine will basically fall over and stall. I let it sit for a minute and then start again. It will start slowly and eventually come back up to the correct RPM depending on when the throttle is. Runs normally for about 3-5 min and does it again. When sitting still, under no load, the engine seems to run normally as best as I can tell. Issue is generally after it is up to temp and under a load. It seems that it has a loss of fuel or possibly an air intrusion issue. I have checked all rubber hoses for blockages and found none. The fuel bowl does not lose any fuel, or fill with air. While running I can crack the injector lines at the pump and the engine falters as it should. Any advise out there, any would be greatly appreciated.
