Surely we’re not the first person this has ever happened to. Our MX4800 just engine just shuts off. It has 200 hours. It has always run fine … until yesterday. Now it runs for a few minutes and shuts off. For twenty minutes it won’t even turn over. Lights function. No error codes. Engine just won’t run. Help. Please. We’re amateurs here.

How is it shutting off? Like running out of fuel or like you turn the key off?

From the no crank situation you probably have a safety switch issue. I would look at the seat safety switch and see if it is working properly.
