Gentlemen,
I have a 2005 TYM Mitsubishi S3L2 engine that when it is just started will work like 100 horses pulling a 7 foot finishing mower. however, once it reaches it's 190 degrees operating temp., it begins to lose power to badly it cannot pull the 7 foot mower raised up off the ground. It hardly has power to pull itself. I have replaced the Primary Full pump and certified it is pumping excellent, changed all fluids , flushed the tank, checked everything possible I dont know what else to check. Only thing left is the injectors, thinking that they may slow up the fuel somehow when at operating temperature, or possible leaky head gasket, and have ruled out valves because it runs so good otherwise. I have not checked the compression because it runs so good colder. IF i let it sit for 15 minutes and restart it , it runs great again. Tractor was sitting for almost 10 years outside in central Florida Weather uncovered prior to me getting it. Fuel to me is ruled out as it pumps out the Primary Fuel pump excellent with a newly installed Spectra Premium A8016EP Deluxe pump when loss of power is occurring. Any help would be good. There are some wires going into the Injector pump from the rear if anyone has any idea what they are for.
Thank You, Michael
