Hi,
Something could be drawing power and draining the battery. Anytime there is an electrical issue, start at the battery. It is the primary power source and a weak one can cause many different issues. Also, make sure the terminals are clean and tight.

Next, if the battery is old, you should remove it and have it load tested at a parts store. Most will do it free of charge.
Also, is it possible for you to record the engine cranking and upload it for me to hear? That may help me identify the issue easier.
Here is one more link you should follow. It explains how to locate and repair a parasitic electrical draw on the battery.

Do these basic checks first and let me know what you find. Next, if possible, record it so I can hear it cranking.
Take care,
Joe
