Have you received any messages in the Google Webmaster tools?

Did you do use blackhat seo techniques? Are these AdSense websites? Google recently updated it's page layout algorithm to go after websites with lots ads above the fold.

Check your Website Optimization Report otherwise. Check your backlinks.

Probably it is because the change in Google algorithms. These changes tend to affect most websites but with proper optimization it will be back to its original position or even better.

Have you used black hat seo techniques to get ranking ?

If you used black hat methods to get to that rank then that may be the reason it has disappeared

Export all of your existing working which was done on your site or a Web Design Company whether through black hat or white hat seo and place the keywords with random keywords relating to your site in order to save your site from getting a penalty through the latest updates.
