85-300SD Battery Drains Dead Nightly?

I am baffled finding direction for a solution with problem. Every morning I need a jump start. I have a new Bosch battery purchased 30 days ago. Once charged it runs for the day. However, when I start the car throughout the day the driver front seat starts to move forward until the car slowly fires backup? This is recent situation and I have not made any significant changes to the 300SD that would affect this situation.

Need troubleshooting advice. Thanks for any guidance.
