how can I repair my pro form 835QT treadmil?

As soon as I step on it, it stops running, I have lubricated the belt,but it didn't help. I put it on high speed and it spins well- however i step on it and take no more than 6-10 steps I here a click and it stops. I remain on it and I here a click and it starts again - I take 3-4 steps and it stops. Does the belt need to be replaced or is the motor or power supply going bad?

done
Change the choke, if it continues then it is the motor. Good luck
