Weird electrical issues

[DSM4DSM]

Hey guys, I'm currently about an hour away from Cincy and plan to head back today. Anyway, last night when I arrived at my destination, I noticed that my headlights wouldn't come on unless I had the engine actually running. Also, stereo wouldn't work either unless engine was on. Wouldn't matter what position I had the key turned, shit wouldn't come on unless engine was actually running. I didn't notice any dimming from lights though when I was driving so not sure what the deal may be. I checked all my fuses and they're all intact. Could this be a ground issue?

Well talk about weird, drove home today and had to stop to pick up some wheels. When I stopped I turned the engine off and tried the headlights and they worked. However, on the drive back to Cincy radio started to cut out (did this last night up to Dayton along with lights cutting off) but otherwise noticed no other problems. Once I got home and shut the car off headlights wouldn't work again and also the motorized seatbelts wouldn't go back to their originaly position. Any ideas?
