electrical issues I think

Well the wife and I were coming back from dinner earlier and jeep just shut off... 91 yj 6 cyl.... I wired my radio into my fuse box under dash and I also have remote start. Completely lost.

No I turn the key and absolutely nothing... doesn't even turn over... I'm gonna try to reset the auto start and see if that is the issue. I'm hoping its something simple. Earlier that day I was working on my radio and when the jeep was running I pulled the dome fuse and it shut off.... so here's to hoping that its a fuse.
