I won't post all of my computer specs, because that's not the problem. It's a good build and this only recently started happening.
The dropout doesn't occur when the audio is by itself on the timeline, or when the video is hidden on the timeline. As soon as the video plays with the audio, the audio drops out after a few seconds. I've tried playing on the lowest playback resolution, doesn't help. My audio is 24 bit, my drivers are up to date, Premiere is up to date. The video gets choppy before the audio drops out. My cache is on the same drive as my footage.
