Motors cutting out

I've had a bamboo gt for little over 7 months and then bought the gtx when it came out. The bamboo had a motor go out with in the first few rides and evolve sent another one and it hasn't given me any issues sense. The gtx from day one has had an issue where one motor will not startup when I go from dead stick. It happens about 6 or so times in a hour long ride. If I let back off then get back on it the motor starts right up every time. I've herd that this is happening to other boards and I just wanted to see if anyone has resolved the issue by change the control board or motors? I think It's my left motor but sometimes I think my right does out to. In gt mode this really can throught the board to one side on a hard acceleration.

 

Mine just did this. I had just changed from an R1 to R2 remote. Was this ever resolved for you?
