Welcome to JUST ANSWER small engines, let me try to help you !! Kohler engine? Electric solenoid in the carburetor? Fuel solenoid closes the main jet in the carburetor. If it looses grip, it will starve engine for fuel and kill engine.Best test is to remove the inner parts of the solenoid, that close the main jet and test with it disabled. It can be getting hot or it can be loosing voltage. Worth looking at.
