I have an LX-279 that keeps dying on my when it gets warm. In the last year I have replaced the fuel pump, carb, water pump, ignition control module, wire harness on the engine (not all to fix this issue but all done recently). Also replace the PTO because I had to break it to remove the motor to do the water pump. I can mow the lawn for about an hour or so. Then all of the sudden the tractor just dies like if you turn off the key. If I can push in the button to turn off the mower deck it will almost die and catch and run again. If I push the button to get the deck working again it typically will die. I am starting to wonder if it is a voltage issue? Any ideas would be amazing as other then this the tractor is working perfectly.
