Hey, Good morning and hope this finds you enjoying the Labor Day weekend. Hoping a reply comes back with some suggestions. I have a 2002 Farmpro 4020 that I have to say has served me well. Certainly had some work to do to achieve that but suddenly my rudimentary + skills aren't figuring out a situation and hoped you could help of give me a number to call and discuss. My tractor will start cold effortlessly and run like a champ~ but almost clock-like, within 12-15 minutes whether under load [brush hog] or riding on a flat packed road- the engine slowly loses power and finally dies. Trying to re-start is a slow rumble and no luck. Like some kind of choke hold. After many hours- will start right back up without hesitation and repeat the same situation again. Temp is fine, levels are fine, can't find a restriction anywhere. I am looking for some "did you check this" ideas . . oh, and I checked that there was no vapor lock of the tank. That is probably the best way to describe the situation symptoms. Like a slow vapor lock and cutting off of the fuel pressure- slowly. Thanks!
