first thing i would look at is fuel filter,probably half plugged, then it would be fuel pump.
check it by putting a fuel pressure guage on the fuel rail and monitor pressure,hopefully your car has a fuel rail monitoring port.

Does driving a car with the a low fuel level affect the car?
Yes it does. The fuel pump is an electric motor that is lubricated and cooled by the fuel surrounding it. It is best to never let the fuel level get below 1/2 of a tank. Also the fuel filter should be changed once a year to prevent excessive pressure build up that causes the pump to overwork and fail prematurely.

Unlikely, Fuel and/or spark are likely culprits.
Can the fuel pump not let my car not to start?
A vehicle with a failed fuel pump will not start. But fuel pumps can have intermediate degrees of failure which can result in intermittent failure or low fuel pressure.
