So I was having the same problem. Intermittent stopping of feed belt. First thing I did was remove the DC drive motor. I then tested it and had the same problem. It would start and stop randomly. I figured that it had to have something to do with the speed controller/DC transformer. I inspected the board (located behind main switch under black cover) and wiggled a few of the components. Tested again and it was totally dead.
This time I opened the speed controller and removed the circuit board and inspected the solder joints. I found 5 that looked suspect. (If you don’t know what a bad one looks like, search google for “broken solder joint”.) I heated up my soldering iron, remelted the solder, put everything back together and it works like a charm.
