Hi , I have a 1988 John deere SX75 w/ a Kawasaki 9 hp engine , it ran fine then it quit getting spark , it has fuel and great compression , but it would start and run a while and quit and not have any spark !!
I replaced the sparp plug , same symptoms , I replaced the coil , same stuff !! The only othe part I can see in the system s a little box called an igniter (that is totally buried , but the mower is in good shape)
What I am wonderinbg is if any one else has had no spark issues with the 9 hp Kaw?? Any sugestions , The igniter costs 63$ , but I see nothing else in the ignition system !! NOTE ,, I did isolate the ignition system on the engine and it acted just the same it would sometimes start and run a couple of minutes and die !!
Thank you in advance for any help on this subject !!

Most likely its the ignitor you are talking about failing when it gets hot. Only thing you can do is replace it.

You can use an after market ignition conversion kit to replace the "igniter" they run around $20.00.
