These symptoms sound very much like https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1842447 (I found the bug I'm commenting on while searching for additional links about the issue in 1842447). There's a -62 kernel in proposed updates which hopefully contains the fix for this bug. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1842447 for hints on how to install the proposed update kernel.

So far the trigger is sounding like NAT + 4.15.0-60 kernel + sufficient time that the relevant uninitialised variable is not clean from boot.

I think this is the fix in -62:
