As a result, for the entire set of words, it seemed like we came up every few searches. And yes, we did check to make sure we didn't run through our budget. In our case, there are only a few bidders, so at most 2 pages of AdWords, so we also investigated this.
So, our conclusion based on this happening just yesterday after 20 months of successful PPC advertising is that if your budget is way lower than Google projects, you can't count on your ad being displayed. To fix this (and it worked) we eliminated the keyword that was throwing the budget off and this problem seemed to go away.
Hope this helps.
