You know that Google page rank is no longer updated via toolbars etc so unless your sites are 2+ years old they'll never show a rank.
Dear, the reason may be you done changes in theme.. of your website.. if you change content or change keywords than it can issue your site is not doing well. in my knowledge this reasons can only be there..
