Hi,
The first thing we need to do is check battery terminals to make sure they are clean and tight. If they are, then check the battery and the alternator.
Here are links for load testing the battery and checking the alternator. Let me know what you find.

Based on your description, it sounds like either we have a bad battery, bad connection, or the alternator isn't charging the battery and causing low voltage to affect different components.
Here is a link you may find helpful when doing the alt test:
