I realized that starting with the most simple area first and work down list: - Vapor Lock - loosen gas cap and see if it runs without issues. If that fixes it buy a new gas cap - Old Gas - drain tank and replace with fresh gas - Fuel System - replace filter, replace fuel lines, replace spark plug. All for under $10 - Electrical - Buy $6 spark plug tester. After it dies, use tester. If no spark, replace ignition coil. Maybe $40 - If still wont start, replace carburetor. Easier in the long run that trying to clean a gummed up one. (most expensive)

The idea to loosening the gas cap was a test to see if the tank is not vented and that's why gas will not flow properly. I think the vent is typically in the cap itself, but it might be vented separately. It's a test, not a solution.

Wait several hours, restart, will run about 10 minutes and then surge and cut out again. Wait a few days and situation duplicates,

Have you changed the oil?
