starting problem-john deere 727A ztrac

[headache]

I have a 727A ztrac zero turn mower. It starts fine when cold, but after it warms up if I shut it off it won't start. It turns over fine but just won't start until it cools off. I have changed fuel filter, oil and air filters, new battery, and plugs. I would like to know if anyone has any ideas what it could be? It has about 425 hrs on engine. Thanks for your help.

Are you getting fire to the spark plug? Sounds like a spark problem with either weak coil or bad electronic ignition coil.

Thanks i'll check on that. good place to start. Never thought about checking fire to plug while warm.
