Losing Power

[rmccroan]

I have a 2009 Mahindra 5525 55hp. Never had a problem until recently. The tractor starts fine and runs fine for 30 min or so while mowing, then it bogs down and seems to lose a lot of power. It gets close to shutting off completely, but doesn't. It limps back to the parking place. I just replace the fuel filter, and air filter, and still it's happening. Any suggestions would be greatly appreciated.

Check the simple possibilities first: Fuel tank venting. When it bogs down, loosen fuel cap. Is there a vacuum? Does engine come back?

I will definitely try that. Thanks!

Does it have an electric supply pump?
