Specific keyword penalty

[MikeMike]

I have had my main page (www.example.com) ranked fairly well for years for my two main keywords.
The last three days I am no where to be found for these two words. I checked site:example.com and it is still indexed. It seems like all my other keywords still rank the same.

The only thing I have changed on the main page is adding google analytics. I did that on sept. 28th. (I sure don't hope that have caused the change).

Is this a penalty on my ranking for those two keywords?
