I have the aforementioned machine and while in use the machine will stop moving and the controls will not respond all the sudden. I have to raise and lower the seat bar but the only code that shows is the left joystick not in neutral. Also, while working the throttle will drop to idle at random times and I have to restart the machine to get throttle response back. The third issue I am having is the auto throttle will not work. Any help would be greatly appreciated. Thanks in advance.
