    motor runs good until it gets warm and then it just quits with no warning. Any and all suggestions would be appreciated.It will start back and run about 100 yards.Been told it could be electric fuel pump. thanks

          update:

          vst has no pressure at all. motor will run and idle for a long period of time. even at a fast idle. when switch is turned on; it sounds like electric pump starts.checked voltage to pump and it measures 12.5 .getting no air or gas out of pressure valve even when pressed with screwdriver.
