Hello from Flint MI. Is your instrument cluster showing any codes where the odometer numbers should be? Any unusual readings when you have it in diagnostic mode? Google Grizzly diagnostic codes and you will find plenty. My friend's Grizzly did the same thing... and then it stalled and wouldn't start.... and this is where it currently sits. If you read my post on my issue, the other comments may help you out. Its in Grizzly Tech Tips, "TPS readings and bulletin". Good luck and please share how you were able to fix your problem.
