engine dies after 20 min use

[gjohn]

2006 bx2350 tractor always starts fine and runs well for 20 min, then power fades quickly and will not tolerate any load demand. I have to throttle back and limp back to the shed at a crawl. Engine temp remains normal, and will restart if it dies. The problem has gotten worse over a few months, I used to get an hour or more.
I have replaced the fuel pump, fuel filters, air filter, changed the oil, and checked other fluids.
It has been to the kabota dealer and they have not been able to diagnose the problem. They thought it was bad fuel.
Any ideas?
extremely frustrated

Is it possible that your fuel tank is not venting, try loosening the cap the next time it start to die on you.

Next time you fill up, put some seafoam or other diesel additive in there. Might be a little water in there and it will help to get rid of it. Could also be something that is plugging your inlet side of the fuel system. It may have dislodged for a while, but now is stuck. May have to drain and flush out the fuel tank with clean fuel.

Hope this helps and good luck!

There is always the possibility of someone putting in gasoline instead of diesel.

Those symptoms are identical to gasoline contamination.
