Fortunately I never went down and was able to come to a stop but the wobble would persist all the way down until I was going maybe 12mph or slower.

By any chance are you tall, with a large bike frame? I talked to some pro racers about it, including the famous Ron Kiefel of the 7-11 Team from the 1980's, and many said it's more common with tall riders and larger frames. I'm 6'4", and ride a 61cm frame. And two of my buddies who have experienced it are also pretty tall. Just wondering.
