Please help, I have a JD GX345, the problem is: the blades keep cutting off. I have replaced the PTO clutch, PTO switch (blade engage), verified seat switch works, ignition box module, ignition time delay module and voltage regulator. Only thing left is an open fuel tank and a match. Thanks for any information y’all provide.

Main symptom is, it's a JD. Think you have a broken wire to the clutch pack. Might be in the insulation jacket. Best diagnostic tool is a multi meter.

Yes, it’s mows for a few minutes, then blades disengage. Wait about 30-45 minutes, starts back up, blades re-engage, mow for few minutes, then blades disengage. Everything else seems to function normally.
