Let me guess, as soon as it sets still for a few hours, it fires straight up again, like there was no problem? :D

If you have one with the Kohler 12.5 Command Pro Engine:

These have a known issue with the ignition pickup/coil assembly. If you feel confident in your skills, removing the upper engine shroud will reveal the coil pack. Loosen the bolts and adjust it's width from the flywheel using a business card as a feeler gauge to set the gap. The card should just *slightly* bind between pickup and flywheel. If it STILL stalls and stumbles and eventually quits AFTER it is hot as you describe, likely the coil pack is tired and worn. Heat will make them short out internally as internal windings expand from heat. Replacement is the only cure. About $40 from Kohler, about $60 from John Deere.

Electric pto will not engage the mowing deck. stopped working while mowing.

had a similar problem. The engine mount bolt that grounded the PTO black ground wire was loose- causing the pto to work erratically. To see this bolt (13mm i think) you will have to lie on your back and look under the machine. It is above the front steering arm of the right tire. If the wire is dangling you will need a new bolt. Thanks for the previous posts ;)

Check the HT lead for cuts or breaks and then replace it anyway then check the on/of switch for rest
