Same thing has happened to me before. I implemented a new set of title tags, google came along and indexed them, I lost alot of my indexed pages. To fix it, I just changed the order of the Title tag back to what it was prior (not exact, but close). Google then ate up my pages and added them back into the index. Maybe it was the $ sign i had as the second word of the tag?
