I have a 2006 997 ZTrak with 2100hrs on it, 72" deck. I've owned it for a year or so and recently started having an issue where the PTO randomly shuts off. Yesterday it was hot (95 degrees), I started mowing and within 15 minutes the engine shut off and the temp light and beeper came on. I turned the key off, restarted and it ran fine for another 10 minutes. Afterwards the PTO then shuts off with the engine reved up, this time no temp light. I idled down restarted the PTO and it ran fine for another 1.5hrs. Yesterday was the first time the engine actually shut off and the light came on but over the last several weeks its randomly shut the PTO down.
Any suggestions on where to start? The engine seems to run fine. I checked the radiator and it didn't appear to be plugged. It has new coolant and I store the machine inside. Its such a random issue I'm having a hard time figuring out where to get started.
Thanks in advance.
