Check the battery cables.

If all of that happened at once I would probably start looking at the BCM.

I would check for power to the fuse box, and bcm. Dont just put a bcm in it without some testing to verify. It is possible that you have a bad connection some where, or some bad fusible links at the starter. So make sure the bcm is getting power!

I had a battery that was shorted one time that had the same exact symptoms you describe.

Yep, my 99' Ws6 did this exact thing. I stopped at a gas station to get a drink & when I came out this is what it did. I replaced the battery & it hasn't done it since. Not sure if a cell went bad in the battery or what.

Start with the cheapest things first, battery & battery cables. Then look at the exciter wire from the alternator, if it's damaged it can effect battery charging.
