2010 Ranger will not start after driving with lights/fog turned on, fine if off.

What is your question?

When I drive with the lights turned off it starts again fine. If I boost it it also starts without any problem after running with the lights on. Starts fine every time I run with the lights off, but the 2 times I've tested driving with my lights on it's like the alternator is not charging the battery. When it doesn't start the interior and dash lights come on but the engine will not turn over and then starts clicking like a dead battery. Once it is jumped seems to charge again fine and starts multiple times if the lights have not been turned on.

What makes this problem better or worse?

Driving with lights/fog lamps on
