Tractor starts up fine and runs for several minutes....then looses power and acceleration. Just drained fuel tank and cleaned filter to remove contaminants. Suggestions to try??

Have you completely bleed the fuel system using the hand pump?

I have not tried this but consider using the hand pump when the tractor starts to weaken to see if fuel delivery is the cause.

take the filter housing off and look inside the inlet where the fuel line goes on. You may find some black goo inside. If you do, clear it out add some algae treatment for diesel to the tank.

Took care of the problem. Ran a small zip tie trough all openings and blew it all out with an air hose. Thank You!!
