There might be a problem in the fuel delivery. Fuel tank vent, fuel hose leaks, primer bulb, fuel filter screen, fuel pump, and lastly the carburator. <br />If all is fine there could be a problem with ignition, electronic ignition cuts out when warm...I've never had this happen, but it's possible. If it were mine I would most suspect the vent or filter...loosen the cap on the tank to check vent. Remove the black plastic cover that is hooked to the fuel line...behind it would be a fine screen and sometimes it can get plugged and not allow enough fuel to carbs...just a Thought

It is a 90% chance it is a wiring issue. Check all connections from the switch to the plugs. Feel each wire to be sure hte insulation is not crmbling away. Many of these engines contained aluminum wiring which corodes from the inside out. If you find insulation that is brittle and not flexible, it is a sure sign of corrosoin inside the insulation. Replace all that is suspect. Good luck.
