I have the above tractor with the Courage 22 engine. I picked it up from somebody that had done some cobble work to it.LOL It runs fine for a bit and then shuts shuts down. Shut key off and start it and dies again pretty much right away. Someone already removed the tip from the electronic fuel shut off so that is not the issue. Tried replacing fuel pump with no luck. I removed the wire from the oil switch and it made no difference. I haven't tried replacing the coils because it generally starts again after it shuts off. Sometimes it doesn't though. Plugs have been replaced. There is no water in the gas. Cleaned all of that. Any suggestions on things I am missing? Could it be a bad coil? Totally puzzled!
