with what i do and don't know, i sounds like something is shorting out or overheating,But, i'll let someone who actually owns a kohler engine give you much better advice!

Replace the ignition module. It's located under the flywheel.

Sounds like a bad Smart Box if it looses spark at both cylinders.
Your engine has two coil modules and chances of them both failing
at the same time are pretty rare. The smart box is hooked up to
both coils and controls ignition timing spark advance.
