I bought a BR600 last fall. I've had a couple of problems with it this year. A few weeks ago, it started shocking me through the handle and started just randomly cutting off. Well, took it back to the dealer the next day, and they put some new parts on it which fixed it. Well, it started cutting off again at random times. Not shocking me, just cutting off. It will do it at full throttle, mid throttle, or just idling. Doesn't matter, it will just cut off. It will also crank back up, as long as you go through the whole choking process again. Has anyone else had this problem? Or is this just a freak thing?
