Kaz Yamauchi responded while retweeting a complaint about Gran Turismo 5′s endurance mode:

I’m sorry. Game saves during endurances. They are currently under development. RT
@andrepeniche: as I simply don’t have 4, 9 or even 24 hours available to stay in front of the TV to do endurance races, as much as I love GT5, unfortunately it’s not possible for me to complete them.
