Well, yep GP down. I have no idea how to diagnose random stalling. Can't throw even one part at it, theres no money. My initial guesses involve removing fuel and ignition system components, looking at and cleaning them and putting them back on and hoping for a change. I am hunting for how to check fuel pressure. Seems like something that could be caused by a clogged fuel filter, but the dash lights dim slightly when it starts to stumble. Whatever it is, it will probably not start before long because going downhill so fast that I think I better work on it in the street so the other cars don't end up blocked in.
