Hey papahaxx, Sorry to hear about your site listing fall. To name a few reasons for this fall might be website age, Number of relevant inbound links, Site content etc., try getting some analysis done through some SEO expert. Google it & you should find help.
You might get sandboxed or has penalty applied to your site. Wait it up cos it may also be google dance, just keep doing what you do now.
looks like your page fell down in ranks i suggest getting backlinks from quality sites to yours that should put in back in place
Did you get any notifications in Google Webmaster Tools? Was it just for one word or for more than one term? I think you should provide more detail for us to understand the situation better. Anyway, no matter what, analyze fully a website, see what could have caused a problem. There are free onpage optimization tools for that, as well as free tools you can check inbound links with. For example, Google Webmaster Tools.
Your pr must have drop,make new posts, generate more back links to increase traffic,there will be improvement.
