I have been using OBS to successfully stream several times a week for the past 3 or more months. Tonight I set up my stream exactly as I always do and this issue surfaced where the kb/s rests at 0 for roughly 10 seconds, then rises to 641+kbp/s and after 1 minute at the most it drops to 0kb/s.
It bounces between 641kb/s and 0kb/s (which is completely useless for streaming) and never recovers.
I have tried the "fixes" I found by searching, including wiping the profiles, using different stream keys, and re-installing OBS. I now have OBS Studio and it did a bit better, getting into the pre-set bitrate of 1500kb/s but after a minute it fell into the same pattern.
Here is an interesting thing that happened: I switched to streaming via a Google+ Hangout and it worked flawlessly (streaming to Youtube). While streaming with the Hangout I set up another live event and streamed using OBS to that new unique stream key. It was streaming perfectly until I clicked "Start Live Stream" on Youtube, Again, after about a minute it ceased to function properly.
I am at a total loss as to how to fix this issue, I haven't found any relevant info through various keyword searches, and I am completely confused as to why the issue started suddenly today.
Here is a log from one of my first attempts (after wiping the profiles):
