OK, I'll take a dive into the network-test-session logs later today.
From your description in comment #9, it sounds like this is the same issue as bug #1418077, where something causes the mobile data connection to drop and NM takes ~5m to restore the connection. If the logs concur with my theory, I will dup this bug and update the other bug to include the scenario where the connection drops on its own ( ie. not triggered by a radio technology change ).
