Hi Moode community 
My MoOde setup: Pi 3B+, official 7" Pi Touchscreen, boot from SD card, music on a USB disk, USB DAC (AudioQuest Dragonfly 1.2), official power supply. No network connection (only during first installation, then no cable). Wifi off, bluetooth off, HDMI off.
History: I have used this same setup for >2 years, cannot even remember how many different versions of MoOde I've gone through. Did not use this setup in the past 15 months (work from home, MoOde at the office), I now did a fresh install of 7.3.
Recurrent scenario: I arrive at work, the Pi is "catatonic". I touch the screen, the image shows after 60 seconds. With a keyboard attached, I use a console with CTRL-ALT-1. No memory free, chromium uses it all. Reboot - all works fine, and before I notice any problems, things work well for quite some time. Never had music stop while playing. I listen with moodeutl -m, memory stays stable at 38-39%. Let playlist finish, screen goes to sleep, I go for lunch -> when I come back the Pi is catatonic again. Repeat from the beginning.
Places I already looked:
With my limited knowledge, I traced the whole thing to chromium eating up the memory, so it would be a bug outside MoOde. But I cannot find what triggers it. Seems to happen only while I'm not using the Pi, so difficult to know.
It seems very similar to the problem described here: http://moodeaudio.org/forum/showthread.php?tid=3331, only it's not an HDMI display, but the official Pi 7" display.
Any hints for further troubleshooting? Running out of ideas... :\ I could try to avoid it? Or try to update chromium? Or go back to 6.7.x and wait until chromium gets fixed...

Places I already looked:
- I ruled out power supply problems, vcgencmd get_throttled reports 0 (no undervoltage occured).
- Ruled out SD card problem, redid the whole setup with a 16 GB card.
- Extended the root file system to the whole 8 GB SD card. Disk free close to 4GB, does not seem to be the problem.
