Vapor lock is when fuel vaporizes in your fuel lines, putting gas (as in gasoline in a gas phase, as opposed to liquid) in parts of your fuel system that need to be full of liquid in order to work properly (like your fuel pump, carburetor, or injectors). This decreases the flow of fuel to the point where your engine can't run.
It is usually caused by some part of the fuel system being exposed to too much heat...like say a fuel line being too close to the exhaust.

When gasoline boils in the fuel line and turns to vapor. Your fuel pump doesn't pump this well, and in fuel injected cars, it compresses more than a liquid would, affecting the amount of fuel getting to the cylinders.
Letting the car cool allows the vapour to condense back to liquid form.

vapor lock in a gas engine, would be when there is vapor in your gas line, as it is going into your cab. this leans out your engine gas mix and causes your engine to run rough normally or with out power.
