When I check the iOS app, both devices are still available and grouped, and the song has finished, but the status is paused/stopped. And when I click Play, it proceeds to the next streamed song in that station (e.g., Prime Country).
In both cases most recently, I generated a diagnostic report as soon as it happened. The numbers are 441323921 and 1971801427.
I'm not sure if this is an issue with Amazon Music getting interrupted; my Internet service; or perhaps the Connect:AMP interference. Can someone from Sonos Support take a look at the diagnostic and let me know if they see anything? I'll continue to add diagnostics to this thread, with additional data points, if it continues to happen.

When I take a closer look at the Command Log, I'm not seeing any stream limits which can rule out another account bumping you off. The wireless environment looks great, so that shouldn't be a problem either. Do you have any Amazon Echo devices that could be attached to the same account?
