This sounds like a ground failure, to me. A very common issue (and also very commonly overlooked) is the very short ground cable that goes from the RF inner fender to the engine, attaching near the alternator. It's hard to see, but if you have or had a broken front engine mount on this car, it's pretty hard on this little cable, and once it breaks, your car simply stops working. Reach down in that area and grab that cable, see if it's broken in two. If necessary, crawl under and put your eyes on it from underneath, so you can see where it attaches. The frayed end may be hard to see, too, at first glance you'll think it's fine, but closer inspection may reveal that there are only a couple strands of copper left holding it together.
