So my dad was using my tractor to brush hog mow.When mowing it lost power and died.Changed the fuel filter thinking it was plugged.Did not help at all.Looked at the old one and it was clean.So here is the funny part let it sit awhile it will fire up and run for 15-30 seconds.Will not throttle up but idle.Take the fuel line off turn the engine over pumps fuel good.Then put the line back on and start it.It will run longer 45 seconds to a minute then die.You guys have any thoughts on my problem?Is it the injector pump? I am going to take it off and have it serviced.Is this the right step? Thanks guys.Big Game today.Go Seahawks.....
