A problem with the fuel system means that your car's engine is not receiving an adequate amount of gas to power it, while a problem with the electrical system means that it is not able to ignite the fuel it is receiving. The car's vacuum system helps maintain optimal pressure between the interior and exterior of the engine, and a crack or leak may cause the engine to stall.
Sometimes, the problem that causes your car to stall can be treated, or at least diagnosed, without a mechanic. Check the tubes and wires leading to and from your engine for any obvious signs of wear or cracking.
