I had the same thing happen to me, running one minute, stop and then no spark. Do the ignition system test (as per manual). Check coil resistance, cdi resistance, source coil 1 and 2 resistance. My bet is source coil will fail the test, which will mean a new stator. That was what happened with mine.
