I have a 1999 Cadillac Deville and I tried to start it the other day and it has no power. I can jump start it and it will run. Turn key off and try later and again no power, nothing. Checked battery, alternator and cleaned battery cables. What should I do next?

Charge battery and have it load tested.

Check the alternator with it running as it should have 14 to 14.5 running.

We did check alternator while it was running. And it did have a 14.5 while running. It baffles me cuz we checked all the obvious. Anymore suggestions I would greatly appreciate it.
