The car starts and then dies after 15 minutes.
This sounds like you may have an issue with your alternator. If your battery is fully charged when the engine is started, but not being charged by the alternator, it will take only 15 minutes or less for the engine to die. When the alternator quits working, all electronics will the run off of the battery. If the battery becomes sufficiently discharged, the engine will no longer run. I would first start by having a YourMechanic technician inspect your starting system. The alternator is the most likely cause but ensure the technician does not neglect the other systems of the vehicle that affect its drivability. These systems would include fuel, ignition, and electrical.
