What are your hardware specifications ?!
And are you 100% sure it's not the Ubiquiti Wireless Bridge having issues for whatever reason ?!
Are you sure you're losing internet access, and it's not just DNS failing?
I ask because I noticed that after 5 to 8 days, and it ended up being Unbound needing to be restarted. Which btw, didn't work properly once Unbound was in a bad state. So I set up a cron job to restart Unbound every 5 days or so.
Just a thought....hope it helps.

4 miles on limited power of wifi, on flat ribbon antenna?
A well tuned yagi probably will struggle. Do those wifi devices provide dBm info (Tx and Rx), I am curious what level the signal is at.
But using that diagram, my guess, an ARP issue is presenting itself. When the problem happens does the ARP tables look ok?
Is that bridge doing actual bridging or proxy-ARP'ing ?
