Polaris SL-750 1993 no spark when hot

[Nohype!]

I have a 1993 SL-750 my wife has owned it for 20 years we had the carbs,fuel lines, oil lines, redone a few years back has great compression. It started doing this end of last year. Starts great when cold, however once it get hot will not restart again until it cools off.. put a new AGM battery in last week.. is it the coils if so where do you get them.. the wires and coils are original..

It likely isn't the coils. You will want to check the readings on the stator with a multimeter to make sure they are within spec. If they check out OK, you should check immediately after the no start condition to see if after running the values change.... :
