It’s not really clear what’s happening from the app’s perspective but it does fail to be able to communicate with the cast device at a certain point.

I would think the most likely culprit was some sort of battery save issue as Android (especially on non-Google devices) can be quite aggressive about it.
If you feel like it, try to generate some clean logs for the issue:
- stop playback (hold pause), force quit the app and restart
- play something to chrome cast
- wait about 15 seconds
- unplug the phone from power
- wait until it stops playing
- capture Plexamp logs
Given that we don’t even see the power (dis)connection, it’s almost certainly something external to the app.
