    Front hub motor stutters

    I have a violamart 1000W 48V front hub motor that has been fine for about 100 miles. Recently it started stuttering and then stopping at first throttle or power assist then running ok if power is applied for a second time and OK there after if the power is kept on. If power is turned off and then on again the motor wil stutter and stop until power is applied a second time. Also noticed a new high whine from the motor when starting out. I checked all of the connections and re-seated the wire harness - they all looked OK. Controller or Motor?
