4300

I have been using my 4300 a lot lately and the motor has turned off and I cant figure out why. It only happens when I have been using it for a while and then when I go over a big bump or rock the engine dies. Some times I can restart it right away but most of the time I have to wait around five minutes. I cant figure it out. I check all the wires and looked for a loose connection but every thing it tight. I initially thought electrical or seat safety button but those have all checked out fine. Any thoughts?

Could be water in the tank. Also, check your fuses to see if one is loose.

Fuel shutoff solenoid/thermistor?

Its there a way I can test the fuel shut off solenoid/thermistor?

Can the safety switch under the seats go bad? I suspect it might not be working wright. Can I bypass it to see?

Just put a jumper wire in the connector. Easy to do, and the way I have run mine for 16 years.

Be careful working on the shut off. The coil in it runs at about 6 volt but pulls in at 12 volt. The thermister reduces the voltage. If you do not reduce the voltage you will find smoke escaping from the valve and its a SOB of a job to get it back in.....

I zip tied the seat safety switch today and ran tractor hard for 3 hours moving rocks. It didn't shut down once. I hope that was the problem.

I had that same symptom once. It turned out to be a loose battery connection. I thought it was the seat safety switch

I actually checked the battery too. I think I may have solved it.
