It worked in the test file I used... but it's not a good approach.

The problem is not with the regex, it's with making assumptions about where the current line is while making changes to the file.

It still does the job, though. I thought about that, but thought that if the gq reformatted some lines the temporary marks that gq uses would be deleted.

Well, you could use a multi-line regex, and the decorate-manipulate-undecorate "design pattern":

%s/^[[:lower:][:punct:]]\{3}\_.\{-}\_^\u/%\r&
g/^%$/normal jgq/^\u^M
g/^%$/d

Note the non-greedy match. One could combine the :g steps.
