Treadmill will trip breaker on the treadmill after 20 to 30 minutes if speed is > 2.3.

Treadmill will run as long as I have the speed < 2.3. If I push the speed higher and or increase the incline to a higher level it will trip the incoming breaker to the treadmill. I have lubricated the belt within the past few months. I used a lubricant called "Spot On" to lubricate it. The treadmill is a Proform 770 EKG model 29166.1.

I believe the motor and the belt need replacing. Wanted a second opinion.
