In InDesign CC 2014.2 I'm trying to either print this document or export it to a PDF. It get's to page 26 and freezes on an .ai document in both scenarios. If I print the range 26-33 everything goes through and it prints or exports. It only get's hung up when printing all of the pages. If I remove the link it gets past that page and just gets hung up on something else. Same thing happens, if I just print or export the range it works. There's nothing weird or erroneous about the files it get hung up on. What's going on here?
It's quite likely a corrupted graphic that needs to be replaced. You have to go through a process of first isolating which page the graphic is one by printing parts to see which parts fail, then isolating down to one page.
Then remove parts of the page to see what part fails.
