not pulling in the entire post text?

Autoblog has been working great for me for about a month. Suddenly, the same feeds that used to supply full-text articles are only showing about 60-80 words, and cutting off. The full text is still in the feed, but it's not getting to the posts. No other changes have been made. The WP site is still set to display the entire post, and no plugin updates have occurred (that I know of) that would change anything.

Here is a link to the feed for the "meds" category:

And here is a post in that category.

You can see that the post contains less than the full text, even though the feed contains more words.

Can you think of any reason this would suddenly stop working perfectly?
thanks in advance
