Stereo receiver to avoid voltage drop
I know someone out there has a solution to this issue. We often camp off grid, that is, solely using 140 watts solar and 2 AGM batteries (Deka) rather than 30 amp shore power. We have a factory instal...

I don't think the item in your first link would provide any benefit, it is for isolating a battery from a system. When you are running your 12V stuff off-grid, you need your batteries connected.
Since the stereo only begins to cut out after a couple hours, then this suggests that everything works normally when your batteries are full. Only after you have discharged them a ways do voltage drop issues occur.
I suspect that some of your other equipment is causing the voltage drop on the system, then your stereo cuts out when that happens. Probably your compressor on your fridge kicking on causing a voltage drop on the system, then your stereo picks that up and shuts down.
Try unplugging/shutting off the fridge next time you are getting intermittent operation from the stereo. See if that stops the stereo from shutting down again.
