this treadmill shuts down on me , it doesnt go black (the lights stay on ) but every counter resets to zero and belt stops moving , they longest run i get is about 7-8 minutes but usually resets in 2-3 minutes i have to start over appox 25-30 times per workout i found that by running in sets (what i call it ) im getting better results because i lift free weights in between i am getting better reults but would still like treadmill to runn properly has any one had this problem and found a fix ? Thank you JD
