When a car is running the alternator is the primary electrical source, and will hold the voltage up at nominal 14V
When you stop, and if a battery cell had died, then the car will be difficult or impossible to start, and all electrical systems may start to go into auto shut down mode to preserve battery power (seen Apollo 13?) The audio system is the first system to shut down due to low battery voltage. I suggest you may have found the problem: battery. Keep driving the car and keep monitoring it PS: make sure you have reset the low battery voltage counters in VIDA, as these alert you to when a battery is getting weak.
