The Yo Yo Effect - is it now getting worse?
[webmasterworld.com...]
And/or... it might also be the latest incarnation or a variant of what had been described for a while as the minus 950 penalty ("-950") or the "end of results penalty". See this discussion...
Google -30 & 950 Penalties - brief summaries
[webmasterworld.com...]
The thread is referenced in the Hot Topics area [webmasterworld.com], which is always pinned to the top of this forum's index page, and you should familiarize yourself with the discussions in those threads.
I've seen something like the effect you describe, affecting pages for their most competitive phrases only, generally in cases where the inbound linking to a page is marginal for the search phrase in question.
The minus 950 discussions are helpful for identifying onpage factors (including site navigation) which sometimes will also trigger such problems.
Disco, when you return to the first page..do you notice a missing "cached" link below your website?
Sorry missed this. It returned a few days after, dropped out again and is currently back. To answer your question, I do see a cached link - but it was cached on July 5th, and it's been jumping back and forth since (and before) then.
Weak inbound linking is also generally a factor (among others) in the kind of volatility you're seeing.
Yahoo shows the site as having 78 K inbound links, though another resource shows 8,770 from 416 domains. Still it does have a good portion of links, and many are deep links. The pages I've observed jumping up and down the results have around 500 links going to that specific page each.
However, I think someone said something about the problem occurring when the anchor text is over-optimized...the site I'm working on has a couple of sitewide links on some big sites. I just checked now, and one of the site it's advertising on accounts for 72K (!) of the inbound external links. However, on that same site there are an exqual number of site wide links to two of our other sites and they're doing fine, so the sitewide link alone can't be to blame...but the site that keeps jumping up and down in rankings only gets 1-2 pages spidered a day, while the other sites (the other two with sitewide links on that huge site) are getting over 100 pages spidered a day.

In my semi-controlled test I change various factors of the website including footer links and the left hand navigation.
To cut to the point, the items that caused that exact type of flux or Yo-Yo were always link related, and in general had to do with one of the following scenarios:
-Too many, or overuse of keywords in the navigation
-Too many, or overuse of keywords in footer links.
-Excessive total number of internal links on the homepage.
-Excessive total number of links linking home with keywords in the link.
Hope this helps.
Reducing the navigation to the main core subcategories can help and is a place I would start with if that appears to be a problem.
The footer is also an easy one to spot - if the footer area is loaded with a lot of links that appear to have no real appeal to the visitor at all and were put into place for SEO in mind, then that might present a problem.
Most times you will find that you can find creative ways to create a taxonomy for the website that gets the right links to the right pages for spidering, isn't overly heavy on keyword links, and most of all, suits the visitor perfectly (which is really the first item you should always consider anyway)
I always try to work with one grouping or change at a time so that you can analyze the results. Changing more than one item takes away from any control in the test and can mes up rankings further if too many large scale changes are made at one time.
Hope this helps.
