Hi, Check that you have the correct spark plug fitted or fit a new one as it sounds like your plug is getting hot then shorting out.
Sometimes the magnito can do this as well. but I would start with the plug.

It may be a problem with the camshaft-compression release. Some of the Briggs & Stratton models had a weak spring on the compression release whis is parts of the camshaft. you may also want tocheck that all wires are clean and tight. Also if it's a over head valve model check the valve clearance.
