New guy here, I’ve had a 773 Bobcat for 3 weeks, I have put 3 hours on it with no problems. Now the machine will just randomly lock up and the “push to operate machine” lights go off. The green button does nothing at that point. I can use the over ride button to move the machine but the lift/tilt do nothing. Shut it off and wait 10-15 minutes and it will run a few more minutes. Codes says “None” any help appreciated.
