Mine is the same way. I was using Feedburner for stats and wasn't sure what Google Analytics did, so I had both on there for a few days. Then I noticed that Feedburner wasn't showing any visitor information, but Analytics was, so I close Analytics to use Feedburner, but the stats never started again.
I know I have had visitors because I have a counter on the page.
I even deleted the Analytics link and closed and reopened the Feedburner feed.
Still, nothing.
My feed is:
