B2910 bogging engine

[Doug57]

I have a Kubota b2910 that runs good for about 10 minutes then engine looses power down to a stall. This just started a week ago. I replaced fuel filter and air filter, didn’t help. Tractor has 1100 hours on it, always garaged when not using. I’m not sure what my next step should be.
Thanks
Doug

Drain some fuel in a glass bottle. Let it settle. Water maybe?

Check vent hole in fuel cap

Check fuel line from tank to filter. Make sure the fitting into the filter assembly is clean, notorious place for collecting crap and reducing fuel flow

I did drain fuel into jar, I did not see any water separation. The fuel has a greenish tint to it. Maybe I got a bad tank of fuel?

You very well could have. Its fuel correct? Doesn’t smell like gasoline?
Cheap enough to drain and dump 2 gallon of fresh. Look to see color when you put it in can.

Good diesel is a greenish tint if it's not offroad.
