Yes. Try exporting your INDD file to INX or IDML, then opening that INX or IDML file back up in the same version of ID. It'll open as an Untitled document. Save it with a new name.
Also try exporting just a spread's worth of stories. You may have a corrupt story file somewhere.
It's always possible that the document is healthy but just constructed very poorly. (I've seen some nightmares.) For example, every line or paragraph is in its own text frame. Or someone accidentally Pasted in Place 50+ times. Other than document corruption, that's the only think I could imagine that would make exporting all stories take so long. Even for long, complex documents, the export shouldn't take longer than a couple minutes, max.
