Motorcycle Repair: V45 Sabre wont start when engine is hot, sabmag, bill silver

Question
I have a 1983 V45 Sabre, 14k miles, generally in VG condition.  Recently problem is that it won't start when hot - takes ~15-30 minutes to cool down, then will start right up.  Starter cranks fine, but engine wont' even try to catch.  Push start works fine.  Don't smell gas, so don't think its flooded.  Any ideas?

Thanks,
Art

Answer
Art, you could be having issues with the KILL switch or wiring to it, but probably you may be experiencing some problems with the spark module overheating or the pulser coils going south when they HOT SOAK after sitting awhile.
