ford 800 loses power

gail brigham · May 26, 2010

My ford 800 loses power after running for about 15 minutes. At first I thought it was vapor-locking (in the middle of a summer day in Louisiana) but now realize that if it stops working hard the engine still will run but won"t take any acceleration or work load. I turn off the PTO and throttle down and it runs okay but will die if I attempt to start bush-hogging again (that is to say, asking the tractor to work hard again). My question is,"Is this an electrical problem or something with the governor?" Thanks to whomever responds!

MOST likely a fuel flow issue but COULD be a weak spark-when-hot issue.

#1 remove the fuel cap and see if that cures it.
#2 Clean the sediment bowl.
#3 Replace the ignition coil.

Well could be a few things. As the others have said. When it starts doing that check your spark it needs to be a blue/white and jump a 1/4 inch gap. If your spark is good check for a vacuum locked tank or a boiling tank either one will case that problem. Also check your fuel flow by removing the drain plug from the bottom of the carb and let it flow for a few minutes catch the gas so as to reuse it and to look at it for rust/dirt/water
