There’s always a very remote possibility of the hardware going bad, but that would be way less than a 1% chance.
If I were to bet, you’re experiencing some sort of wifi interference issue. Without more details, it’s hard to tell, but one thing I’d suggest is that you stop doing a “master reset”, more commonly called a factory reset. It tends not to fix things, just obfuscate the issues by erasing the data stored on the device that would help Sonos help you figure it out.
A few things that might help the community help you, if you prefer not to submit a system diagnostic and talk to Sonos about what they find, would be knowing how your Sonos is connected to your LAN. Do you have a device wired? Or does it just connect to your Wifi signal? What kind of wifi network do you have, is it a standard single point router, or are you running a mesh network? Do you have any Powerline adapters in use, or other network extenders? Do you have any other Sonos devices in use?
