Grasshopper 725 runs great for about 20-30 minutes then just dies. It then has to sit until it cools t o restart. Had a new coil put it and still continues. During the time it sits it does not have spark. Any ideas?

Which engine does it have?

Is this electronic ignition or older points, condenser and coil system?

I believe it’s a Kubota

Clogged fuel filters will exhibit that symptom.

Kubby 3 cylinder gasser... I'd say clogged fuel filter or bad condenser. Could be a gunked carb from bad e-gas as well.

Fogged fuel filter would? It doesn’t spark after it shuts down.
