I was driving my 73 Cadillac hearse home and She just cutoff. This is the second time this has happened. The first time was Sun. I was heading back from the Stone Mountain Ga meet on the interstate running about 70-75 mph and She just cutoff. I pulled to the side of the road and turned the key and She spun over, but wouldn't fire. I waited less than a minute and tried again and She fired up and drove the rest of the way no problem. Tonight I was less than a mile from home coming back from a cruise in. I was going about 45 mph and She just cutoff. I tried to crank Her. She spun over, but would not start. I waited for a minute or so and still would not start. Had to pull Her home and poured some gas in the carb, still nothing. Keep trying and finally She started. Does anybody have any suggestions as what the problem could be? No points, have a points eliminator, that was put on a couple years ago.
