I'm having the exact same problem. Strange too- it's not consistent. One layout will work then the next time it won't. Then I'll find a scratch file somewhere that seems to be an ok file. I open it in acrobat and save as pdf... then it's fine.
Could it be the fills? More often the sheets with fills (sections/ elevations/ siteplans) crash. Most of the time the floor plans are ok, but now those too crash.
I even tried saving as PDF outside the publisher. Still crashed.
