Wanted to provide an update. I seem to have resolved the problem by doing three things. Not sure if one of these things corrected it or if all together solved the problem. First, be sure to run OBS as administrator - you have to turn the flag on in the shortcut. In OBS, Settings, Output, I went into the advanced form, and turned encoding from x264 to QuickSync H.264, and in Settings, Advanced, I turned on the "Dynamically change bitrate to manage congestion" on.
