Would an alternator cause a car to stall while driving?

Yes, a failing alternator can cause a car to stall while driving. The alternator is responsible for charging the battery and powering the electrical systems; if it fails, the battery can become depleted. As the electrical systems begin to falter, the engine may lose power, leading to a stall. Additionally, a weak alternator can cause issues with the ignition system, further contributing to stalling.
