You probably need to get the carburetor taken apart & cleaned out;Lol. Thats it. It just conks out. It starts back up after a moment- like Colonel lol- it didnt flush when we got it home but my arms were done after fighting the current at the ramp.
When you don't flush the fuel (which is mixed with oil on a 2 stroke) the jets in the carburetor get all gummed up with that old fuel/oil mixture sitting in them.
It wouldn't be a bad idea to put new spark plugs & a new fuel filter in it too.
