Just to update–I started having more aggressive frequent shutdowns and logs don’t show anything. I figured to try upping the 12V 2A powersupply to 3A thinking that the Yellow+CM5+nvme+z-wave USB stick might be drawing more than 24W… So far the system is not shutting down unexpectedly with this change (+2days so far!). I went with the 2A since that was from the spec sheet / online but maybe for stability +3A might be better…
