This link is for Skyrim, but still applies to FO4:
tl;dr There is a limit to the number of references that can be loaded into memory. Running a lot of mods that add objects to the game that make heavy world edits or add large numbers of cells that are not master files seems to be the cause of infinite load screens/CTDs. You can run this script in xEdit (FO4Edit) to see if you are exceeding this limit.
The other interesting bit is that even temporary references in esps are persistent in memory and count toward the limit of loaded references.
