Too much friction on the running belt can cause the belt to heat up and not run properly. Treadmills require lubrication to limit the amount of friction between the platform and belt. When the friction increases to a certain point, the machine is automatically set to power off. This may be the cause for the machine to stop working suddenly. Try to lubricate the belt to see if the problem is fixed. Ultimately, the hard-wired V-Belt
may need to be replaced.
