Follow the ground wire from the battery to the engine, from the engine to the chassis and then at the lower control box. Clean and tightly attach the connections. Do the same for the Positive lead from the battery to the Starter and from there to the lower control box and other connections. "All of a sudden", "sometimes", and "out of nowhere" usually end up being loose or filthy connections. once this is verified, we can start in with the fun stuff!
thanks ill try that
Mojo is spot on, more than once I have found bad battery ground connections. Don't just "visually" inspect it, take the battery frame connection loose, clean it, and reconnect. So many times, bad cable terminal connections will shut down all operations of a machine.
