That's a big thing to start at. Could be a loose UVCH making intermittent connection making it seem as though it's missing. U joint. Trans. Diff. Drive shaft. Could be the EBPV closing when cold like it should. You could unplug it from the base of the pedestal and see if it stops.
I replied to your other one.
