I have tried with the kill wires off and it idled beutifully until it got hot and then just shut down , it wouldn't start again untill it cooled down. I also tried with kill wires on and exactly the same thing happened . So once it cooled down again I took the kill wires of again it ran till it got hot,so I'm pretty sure it would be the coil as after it ran I had taken the spark plug out and tested iton the engine and no spark at all when it was hot. Tried with several spark plugs with the same result. Coil =$ cheers and I hope your coil is the same
