Assuming you do not have the headlights on while the ignition is off:
The first suspect is always the battery. Have it checked out, preferably under a load. This can be done at just about any auto parts store.
Second, have the alternator checked to make sure it is putting out sufficient amperage. Most alternators are actually rebuilt, not new.
Third, check your connections from the alternator and the battery. Dirty or poor connections can cause problems.
Fourth, it is possible that there is a short somewhere that is drawing power. A competent mechanic familiar with auto electronics can find it.

Why does my 1994 Pontiac Sunbird die at stop signslights?
maybe its your alternator, if its giving off a weak enough charge, when you put the brake lights on, it drains too much power to run your engine. to check the alternator, start car, and remove the positive cable from your battery with some accesories running. if your car sputters, or stalls, just replace the alternator. hope this helps.

The cells in your battery could be dying, instead of buying one, use someones to try it, if it drains that one it sounds as though your altanator is shot. Good luck.

Because you left the lights on all night. This drains the battery. Connect a battery charger and wait about 3 hours. Then the car might start. If it does not start buy a new battery or a new car whichever you prefer.battery juice is gone.
