I finally discovered my issue was due to a bad battery. My laptop has 2 batteries in it and the 2nd one (replaces the dvd) had gone bad. So while I could run on battery, if I pulled the power cord, I think it tried to power from the bad battery first somehow and the power was cut. Once I removed the defective battery, everything works fine.
