Pi-Hole / Raspberry Pi randomly freezing & disconnecting

After switching to using Pi-Hole as my DHCP server, it seems to work for a bit, then the Raspberry Pi will freeze and seems to disconnect from the network for some time, then after several minutes seems to spontaneously re-connect

Expected Behaviour:

standard install using the provided install script - worked well while my router was setup as the DHCP server and Pi-Hole as the DNS for the router, did not notice any downtime

Actual Behaviour:

Whole machine randomly freezes and disconnects, then randomly re-connects. Not seeing anything jumping out at me in the logs in the UI (when it's up)

How does your swap file usage look. I've seen similar with underpowered and overloaded RPi where swap file was constantly at 100%. The overloading was caused by me having too much stuff running on the Rpi.
