Mower shutting down within 20-30 minutes

[Horsey851]

Hi all,
I am hoping someone can give me an idea of what may be happening. I have a ZG23 zero turn mower. Ran great all season last year except the last three weeks. I would start mowing and 20-30 minutes later it would shut down. It will restart no problem and run all day long until I engage the PTO. At that point it shouts down again. Please help.

Sounds like a faulty safety switch, in the seat most likely........

Check the seat switch.
