Was running full throttle when the engine died, no warning buzzer or anything. Couldn't get it restarted. Read all lot of posts about similiar problems, cut the black and yellow wire (kill) going to the power pack and it started right up, but was only running on one one side. Bought a new pack, same problem. Disconnected the neutral safety switch, replaced the key switch, same thing. I run premix so its not a low oil problem, and its running cool. Running out of ideas and would appreciate any feedback...
