Narrative:

The aircraft's right engine driven generator was deferred earlier in the day. The APU was running and supplying electrical power to the right a/c bus. At approximately 40 KTS on the takeoff roll the APU shut down. Given that we were assigned a complex RNAV departure in busy airspace and having only one source of power; I rejected the takeoff. The reject was performed before the throttles had clamped.I taxied clear of the runway and restarted the APU. I contacted dispatch; maintenance; and the duty pilot. The APU was running and stable. We agreed to continue with the flight. The next takeoff was uneventful and the APU stayed running for the remainder of the flight. A review of the item in the logbook; a few days later; showed that maintenance found the APU oil low.
