CHARGING SYSTEM FAILURE

2005 Buick Terraza • 125,000 miles

I was driving at night and the radio went off, the headlights went out, it felt as if I had no power, but the van didn't die. The charging system failure light came on, also the ABS Service ABS light and the Battery Saver active light came on. I pulled to the side of the road and reved up the engine. I regained power again and drove home.
Next day, it left me stranded and only clicked when I tried to start it.
Replaced the battery and it started. Twice the Charging system failure light has come on at two different times.
I manually turn off the lights so as not to drain the battery while driving.
Could the alternator be bad, just charging intermittingly?

Have the alternator load tested to find out if its defective

The alternator has been tested along with the battery. Both showed good.

Both tested good -Have the computer controlled circuit of the alternator field generation checked and tested-double check all connections-
