It is usually caused by heat, causing the gasoline to vaporize, which when your fuel pump is in the tank, means you have air bubbles in the fuel pump that will not allow the pump to get suction. This can usually be reduced by making sure your fuel tank is full on extremely hot days, which will reduce the chance of vapor lock. Vapor lock on a vehcile with a mechanical fuel pump on the other hand, usually requires you to keep a quart bottle of gasoline in the trunk to pour into the carb to prime it with, so the pump can gain suction again.

Ok my 2 cents.
It is when the fuel line (usually the steel) gets too hot and can't dissipate the heat. the fuel will actually turn to vapor as it can in the fuel line then when it gets to the carb there is no fuel so the vehicle dies. or sputters. the last car I saw this on were the fiero's their fule lines passed by the exhaust and if the heat shield was gone trouble started. I would hang the metal binder clips on the fuel line until I could get a ribbed fuel line replacement in aluminum or stainless to make the car go.
Like previously stated with fuel injection the fuel is pushed not pulled to the engine.....Oh geez ya see it's been a long time. this happens on mostly mechanical fuel pumps also. so to eliminate it on a carbed engine get an inline electric fuel pump this should help keep the fuel moving.

To prevent fuel not flowing to the engine (vapor lock) Pilots turn on the boost pump prior to take off or when changing fuel tanks to avoid full flow problems.

Vapor lock is when the fuel forms a bubble in the fuel line. It is common on older cars that have metal fuel lines. It is not to common on cars today because they have high pressure rubber lines. It is caused by excessive heat. Jus let the car set for awhile and let the gas in the line cool and it will drain back to the tank.

thats where the fuel turns to vapor before it gets to the carburator, but your question would be

pretty rare these days as most fuelinjection systems recirculate the unused fuel back to the tank and are under greater pressure

when your fuel gets hot and , you get air into your fule line and your car wont start
