Sounds like it could be a number of things Coil breaking down,ignition module breaking down or a failing relay.Could be ignition relay or fuel pump relay.The relay is the quickest,easiest and cheapest option to try first.

First, DON"T check your alternator that way anymore. It's not good to do on newer systems! The best, quickest check I can tell you is to put a volt meter across the battery. Running with accessories off you should see voltage of about 13.5 to 14.5.
With all accessories and headlamps on high turned on, it should not drop below 12.5. (and that is the absolute low end!).
It sounds like something in the car is staying on. check the glovebox light and interior light delay and make sure they are OK. Otherwise, you will have to start checking entire system for a draw that's taking out the battery overnight. To check, you can pull one fuse at a time and see if draw goes away, then check system that fuse serves.

Many possibilities but the alternator is a good place to start, if its plug is loose, then the green relay inside the center console just to the left and slightly in front of the emergency brake will be clicking in connecting and disconnecting the battery( one loud click per time). It will need replacing or simply disconnecting works for the short budget.
