I seem to have a parasitic loss somewhere that is killing my battery after 3 or 4 days.
When I charge the batteries and start it up my hazards are flashing.
The button on the steering wheel is NOT depressed, and they weren't on before the battery died. (I'm not the sharpest spoon in the drawer but I'd notice the flashers on...)
Any suggestions on where to look?
No recent changes to the electrical system.

I would find the fuse that controls the flashers (and maybe something else), pull it, and see if there is a change. Also, test to see if that circuit is the problem with your parasitic draw.
