Why Does My Car Battery Die Overnight. Even if youve already ruled out obvious things like the headlights and dome light there may still be a drain in your system. A car can die while driving but then will often restart if there are problems with the battery or alternator a lack of fuel a broken timing belt problems with the fuel delivery system or if the engine over heats.
