Thank you for your responses. I will answer each question. The electrical componants were replaced because of this problem. The floats were checked and all seems well. The fuel in the bowls is at the top of the bowl as it should be. The engine restarts immediately but continues to cut out or shut itself off. The rpm's don't seem to matter. It will cut out at idle or at WOT if the engine has been running for awhile. When I first start it up it runs fine at any rpm. The TPS has been disconnected for years so I reconnected it to see if that would help but it does not help. I will check the plugs tomorrow and report what I find. If there was a vacuum leak, would it only effect the bike when it was hot? I know I'm drawing at straws here. All the squarrel condums are new and firmly seated.
