Looks like case of sandbox, how old is your site? Try to add some new content and do some back linking.
Yep, sounds like an ugly case of sand boxing. Unfortunately this happens a lot. I understand how frustrating it can be. You get all excited b/c you site shows up in a good spot, then within days it is gone. Just keep positive. Unfortunately the only cure is to keep building good quality back links, and patience...b/c it will take some time.
clear case of sandboxing ...it seems that you have gained too much backlinks for your site and because of these google has sandboxed you for checking the links ...you just do one thing...manage to get the same no of links and maintaine the same link velocity ..only this way youwill come out from the sandbox and once you come out from this you will get high rank for most of your k/w...
