I have a ProForm 830QT treadmill and after using for about 15 minutes it suddenly turns off. After about a minute or so I have to reset the fuse on the front of the machine just over the on/off switch and it starts again but will then turn off again when I go to a higher speed. Any suggestions on what might be wrong and how to fix it.
