I'd guess hard drive space allocation with the clues given.
Of course Mac already asked that.

A new file is not the same as a pre-existing one. With a pre-existing one you start including 'undo' and such that requires storage to accomplish.
If you open a new file and generate a song, save, and then start re-generating again I'd bet the same issue occurs. Or at least it's a way to test the theory.
