I have noticed this same phenomena on the PS3 version as well.Honestly, because the game has so many glitches that remain totally unfixed. its a serious problem that is one of the major downfalls of the game in my opinion. it makes it unbearable sometimes. but... thats my guess because it happens to me frequently as well
That isn't just exclusive to Fallout, the same goes for Oblivion (Same creators/engine as Fallout).
When the loading times are getting longer and longer, just restart your console, and if you're playing on the Xbox 360, it's wise to install it.
