Sorry to hear of this, Alan. However, I'll bet Richard's guess about the alarm system draining the battery will in fact turn out to be the culprit here.
Whatever it turns out to be, I sure hope your dealer's techs will be able to locate and rectify the exact problem so that you'll be able to then give your America a second chance at putting many a trouble-free and enjoyable mile on her in the future.
(...I mean, sometimes one must wait until Act II to see if they're really going to like how things play out, ya know!)
