JD RX75 ride on mower problem

[Leon R]

My mower has a 9hp Kawasaki motor with electronic ignition. Having problems with it losing its ignition spark after it runs for a while. It will stop without any warning. let it sit for 15 to 20 minutes and it will go again. When I check the spark at the plug after it had died the spark is very weak, almost none existent. When it is running it runs fine with a strong spark. I thought that it was the coil so replaced it with a new one and still have the problem. What else in the ignition system can be causing it to shut down??? I did post on the YT tractor forum however have not come up with anything other than the coil pack.

Is there rust on the magnet used with the coil on the flywheel? Have seen that be a problem before. Just used emeory cloth to remove it.
