Problem is, the engine loses power after running for shot time (3-5 min.) Had the injector pump and injectors checked out by diesel shop. They checked out OK. Replaced new head gasket because the injector shields were replaced. Couldn't get old ones out without pulling the head. I pulled the muffler thinking it maybe rusted and coked up?
Still loses power after shot period of time. This is a Yanmar 3 Cylinder Engine (Modle=3TNA72UJ)Grass is growing great. It's almost as long as a plush wheat field.

Check engine compression. Change air filters and fuel filters. Look for vacuum leaks. All of these will cause a loss in engine performance.

My F935 did the same thing. After three trips to a service shop, I finally found a service shop who knew what was wrong. The fuel shutoff valve needed to be adjusted. Don't know how to adjust it but they did and it runs great. Also make sure you have new rubber pickup hoses in the tanks and your fuel assembly pipe in the tank doesn't have holes in it. Ever tyr to suck up a coke with a straw that has a small hole in it? Can't maintain suction. Same for your fuel system
