Fuel tank has to vent, but loosening the fuel cap would be the test. I doubt that is the problem. How long before it will restart? There is an electric fuel solenoid in the carburetor on most late model Briggs engines, that has to open the main jet as soon as the key is turned on. It has to stay open as long as the key is on. Requires 12 volts to stay open. It may be closing and shutting of the fuel supply.
I see a second question, is this one not showing?
