Hi,
Fuel tank air vent?

Yes. Good point. Try running it with the fuel cap slackened off.


If it was the fuel tank air vent (and the resulting vacuum that would
prevent fuel from getting to the engine) then it would not start right
back up as the OP describes, it would take a period of time as the
engine cools off and the air very slowly gets back into the fuel tank
to break the vacuum before it would start up again...
