I've had a incidents where a page disappeared for certain phrases while it still ranked well for simular pharses. Sometimes these things come and go and are not worth spending a lot of time on.
If it's an important phrase see if you can get some inbound links with the missing phrase in the anchor text. Don't overdo it.
You can also change some of your internal links to reflect the missing phrase.
Sometimes it works and sometimes it doesn't. I think it is sometimes caused by glitch of some sort rather than a penalty.

Also mentioned here [webmasterworld.com...]
This "disappearing for some searches but not others" phenomenon happened in a widespread fashion a few months ago.
The URL only part for your page though is not something I've seen with other pages though. That URL phenomenon happens briefly sometimes though when they are updating like today, so perhaps it won't continue for you.

Interesting to note that this behavior echoes part of what websites experience that we call the sandbox effect. And way back when it ws first being noticed, GoogleGuy did say that the effect was a combined result of several different filters. So perhaps just one of those filters has been dialed up a bit?

Checking back today all seems to be back to normal. Very strange, but will keep an eye on it.

I've noticed this happening with my websites too. Occasionally it will disappear or move to the second page on some searches but remain #1 or top 5 on others, also the results will change drastically so instead of returning 50,000,000 with the search it is only bringing in 28,000,000 results so I figured it is Google tweaking the filters.
I don't worry about it as it usually works itself out again.
