My stx38 with black mower deck starts quickly and runs well

Customer Question

My stx38 with black mower deck starts quickly and runs well for about 5 minutes, then stops like I turned off the key. If I wait about 1 hour, it will start again, but after about 5 minutes it cuts out. Can you help?
JA: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Once the engine cuts out, do you have spark at the plug? If you have not checked this yet, check for spark after engine dies out and let me know please.

okay, this tells me the coil is cutting out and needs replaced. A new Ignition module (COIL) should fix your issue
