I've had mine a bit over a month but only about 50 miles on it. I just had the same thing happen to me but as I was riding. I was in PAS 3 and suddenly I was riding a brick on wheels. All the readings were normal, if I changed the PAS it indicated it but no help and no throttle. I turned around to go back home and realized that wasn't going to fly so I stopped and shut it off. When I turned it back on everything worked again. Didn't happen again but I certainly don't have a warm fuzzy feeling about getting too far from home. I'll be calling tech support in the morning.
