I have replaced the filters and they remain clean this is a well cared for machine .Dealer replaced filters and charged me a bunch. does any body really have an intelligent idea. Could it be a relay and if so which one?
Check to make sure the fuel shut off solonoid is working correctly. It may be getting worn out and as it heats up it doesn't work correctly. We had a Deere skid steer do that to us, it eventually wouldn't start at all.
