First, If this is a 10 hour job, I am little confused as to why maui is not
charging 96*10*3600. As far as I knew, maui charges by second and not by
hour.

What does a checkjob -v on the job say is the reason for the deferral?

I am not sure, but it would be a problem in maui for leaving the
reservations around (or a problem in the prolog and epilog scripts since I
don't see how maui is going to be charging 960 for the job). One
improvement that we made in Moab was in linking the jobs up better. When
Maui was written, if a job tried to start multiple times, it could easily
wind up creating multiple reservations. Later we added some flags to Gold
to better address this situation (Moab calls Job Reserve with the
Replace:=True flag which deletes any reservations of the same name before
creating a new reservation). I suspect that either this is the problem (and
you are using an edited version of maui for the hours thing) or that you
are using prologs and epilogs which do not call the Replace option.
