Jim - I forwarded your question to the ascent FDO for that flight and
got this response:

Yeah, he probably is thinking of STS-93. It was Eileen's first CDR
flight...We shutdown .15 seconds early resulting in the 15fps
underspeed. No real impact on-orbit. All low level sensors flashed
dry resulting in the shutdown. It was caused by a combination of being
on the low side of the tanking estimate and the nozzle leak.

I recall that there's been at least one actual
shuttle launch where a low-level sensor triggered
shutdown earlier than scheduled -- but nobody seems
to have any record of this at NASA. Does anyone
else recall which flight this was?

I'm remembering it was an ISS mission, and the
shutdown was within a few tenths of a second of the nominal one,
so there was not any significant orbital impact and the mission
proceded as planned.
