[Cobra 29]

I need to understand what happened. I was driving today in 95 degree weather, engine temp was around 180, have 1/2 tank of gas. Nearing home the engine sputtered and stop dead 50 feet from the drive way (of course it is uphill to the drive). On the third or fourth restart the engine ran briefly to get us home.

Upon inspection there was little or no gas in the front bowl. The electric gas pump ran continuously. I disconnected the fuel line to the carb to test the gas flow. At first nothing then the pump primed itself and gas began to flow. I reconnected the fuel line and the engine started with no problems. No time for a test drive to throughly test.

What happened? Is this vapor lock? If so, how to I prevent? Many times I take my kids (one at a time) with me on drives. I need reliability!
