Engine Dies

I have a Howard Price 360Z mower.

Last time while I was mowing, the engine just dies. I had been mowing for about an hour. I shut off the blade, turn off the key and set the brake. I open the seat compartment thinking it was the seat switch. Got back on and it started right up.
after mowing a strip, it did it again. Repeated the process several more times before I limped it back to the garage.

Thinking it was the seat switch that was arcing by the seat bouncing up and down, I replaced the seat switch. I mowed again today and after an hour and a half, if cut out again.
I didn't get off this time but only disengaged the blade and set the brake. Started up after a little cranking. Mowed another strip and then it died. Repeated the process. When it started to die while mowing this time, I pushed it the blade disengage switch, it sputtered, but did not die. I mowed a few yards, it started to die, but this time pushing the mower button didn't help. It died again.

It sounds like an electrical problem. Has this happened on any zero turn?

Any ideas?

I wonder if that's the problem. I'd try opening it the next time the engine dies. Or switch back to the old one. See if that helps.

does sound like a cut in reverse safety switch doing it or the key switch has issues with that cut in reverse part of it

You can only learn if you ask the question, so there are no dumb questions.

It's a dual tank mower so I doubt if that (both) is the problem. But I'll give it a try anyway.

I ran across this. Mine is acting similarly:

I'm going to put the charger on to day to see if it needs charging and then charge the battery right before I mow next time.

Does not have a 'cut in reverse' safety switch.

When you replaced the fuel cap did you clean the crud out of tank ?
Also remove the tank switch & clean it out.
Floating debris clogs the outlets then when sitting the debris floats away.

Got through the whole yard without it cutting out on me. It was 10 degrees cooler, but I don't think that makes a difference to an engine. I had changed the fuel filter, which looked dark. The pre-filter on the air filter was covered in grass. I also cleaned out around the engine. The fins around the spark plug looked clear, but if it does it again, I'll pop the top and clean it out better.

Thanks
