Default Re: Vapor lock, possibly?

My experience 99% of the time; bad condenser. All available condensers are made overseas with very poor quality, workmanship and substandard materials. Some are bad right out of the box. One time it was a bad ignition coil. Make sure you don't have something blocking the gas tank vent tube (which exits near the gas cap). Could also be so much crud in the bottom of the gas tank that the crud gets sucked into the copper screen/sock, blocking gas from exiting the tank (until you shut off the engine, then the crud falls off the sock and allows starting again).
Heat is the main enemy of the offshore coils and condensers. Try to keep engine coolant level to provide a normal operating temperature below 190 degrees F. I use 160 degree thermostats.
