I have had a similar issue, not exactly with the same device, but with other Bluetooth devices. Here's my take - this issue occurs when the phone gets to a certain temperature and causes instability with the Bluetooth module in the phone. When the phone's temperature is low, around 30-35 C, the phone works perfectly, but adding additional payload such as streaming music and/or recording drives from a dashcam to your phone, this causes the phone's internal temperature to increase, therefore audio streamed through Bluetooth devices cuts in and out. Additionally, another symptom of this has been the phone disconnecting from Android Auto and sometimes reconnecting, but in many cases failing to do so because the phone is just too warm.
For context, I have experienced this issue on a pair of Bluetooth earbuds, a Jam Classic Bluetooth speaker, in my 2018 Kia Optima, and in my 2023 Kia Seltos. Calls as mentioned in this thread seem to be unaffected, it is just listening to music through Pandora, Spotify, Amazon Music and other apps. In my troubleshooting, clearing app cache, wiping the cache partition and resetting the network settings on the phone provide no improvement. Doing a factory reset of the phone results in the same performance degradation.
Another thing to note is this problem has been present since my Samsung Galaxy S9. Currently, I own a Galaxy S22 and also had a Galaxy S21. I love Android, and I want to say I love Samsung phones, but that many generations of phones with the same problem and the issue not being resolved is unacceptable. This issue ruins the user experience. I had a Pixel 7 for a short period of time, and that phone never had the issue I experience with audio cutting out. This is the same performance I would expect from a brand like Samsung, one that is supposed to be a pioneer in the phone industry.
