If you can check the voltage of the battery with a multimeter do so, should be around 13.5 volts, check again with car running, and the voltage maybe higher still, proving the alternator works . If the voltage is 12volts or less then your battery needs replacing. As your car runs after a jump start but fails again after it is stopped I would guess it is time to renew it.
If the battery is more than three years old I recommend that you just replace it. Otherwise, take it to any reputable shop and have them run a battery/charging system check.
