I posted a problem about a month ago with my Kohler M18 having an intermittent problem losing spark. Each time this ocurred I've been able to eliminate one more thing, and last time I concluded it had to be the ignition module. After I spent three hours getting all the shrouds and covers out of the way to get at the module, I took it out and tested the secondary side again. It would fluctuate between 20Kohm and open as I flexed the plug wire where it enters the module. So the wire was the actual problem and it's an integral part of the module. $80 later I'm back in business. Thanks for all who offered help with the diagnosis.
