Twin engine Kohler. It will not loose spark unless it has the oil guard system.. So it likley is a fuel supply problem. Is the fuel tank venting? It is not drawing a vacuum on the tank? Do you see fuel in the fuel filter when it quits? How long before it will restart? The carburetor has an electric solenoid, which closes the main jet in the carburetor when it is closed. It has to stay open as long as the key is on. It can be loosing voltage, or it can be overheating and shutting off.
