Sounds like a classic case of vapor lock, fuel is vaporizing in the fuel line and can no longer flow like a liquid, especially if you still have a mechanical fuel pump/carburetor (fuel pump will just suck vapor/air). Check if there is something causing excessive heat near the fuel line. Higher ethanol fuel is more prone to vapor lock.
