Car suddenly dies. Still has power but loses some electrical functions.
I was sitting in my car while it was parked and running. Suddenly engine shuts off. Cranks but doesn’t start anymore. Radio and windows stopped working, but other electric functions like lights all working. About 5-10 minutes later my drivers window rolls down all the way and I was able to start my car again and everything functioned as normal. This has happened twice so far. Battery was recently changed.

2001 SL500. I just replaced the cps a few months ago. Was having a similar problem. Before, engine would shut off but every electric functioned properly. Now, when it shuts off, windows and radio don’t function.
