While running my Suzuki DF 60 (2000 model) yesterday, the engine shut off at 4800 rpm after running fine for 15 minutes (almost as if the ignition was cut off). The first thing I did was to check the kill switch but it hadn't been activated. I was able to start the motor, but it died out again. After 5 minutes or so, it started and died once I engaged the throttle. Now, the motor will turn over fine but will not fire. Any ideas, maybe a bad fuel pump bad? I recently had water in the fuel and had the fuel system, valves, and fuel pump replaced.
