    I had strange/intermittent issues that were solved by taking my machine (gas, not diesel) to a battery shop. They diagnosed a bad ground cable (simple, huh?!?) from the block to the neg post. Problems solved. Hope this helps...best of luck.

    Could it be the fuel shut off solenoid? Is there a way to test it?

    On my Yanmar 3TNV88, I replaced a circuit breaker two times -- at 1380 hrs and 1910 hrs. As I recall it quit running after a half hour or so and would restart after sitting for 20 minutes or so. My Dixie dealer is also a John Deere dealer. He wired in a C-021 circuit breaker but I don't know for sure what brand it is. The circuit breaker is near the starter.

    I also replace the fuel shut off solenoid at 2020 hrs. The wiring and insulation had gotten hot. I have another 230 hrs on the mower with no problems so far.
