Oddly enough, P, this brings back memories of a Plymouth Arrow (yes, I owned one when I was a poor young man. I'm deeply ashamed........) I had a looooong time ago. Beyond the fact that it was already a POS when I bought it, it had this annoying habit of dying when I'd be pulling put of the driveway. It would start fine, run OK (it never really ran OK) & then die just as I'd be pulling out on the street. Eventually, after much troubleshooting & false starts, I ended-up replacing the alternator & never had the problem again. I was never really sure what solved the problem but now it seems entirely possible, decades later, that it was the alternator all along.

Good luck with the replacement & thanks for the follow-up report!!!
