My Dart 351W has developed a new trick. It happens when for instance I pull out of a driveway and see a red light ahead. I accelerate moderately hard in first gear, then just drop my foot off the gas to coast to the red light. As soon as I drop my foot off the gas, the engine dies. Just stops dead, like I turned the ignition key off. No stumble, just dead. If I put it in neutral, it starts right back up, but occasionally with a bit of a stumble on startup before it idles smoothly again. If I accelerate through the gears, slow or really pushing it, it doesn't die. Only under the sort of situation I described above. My first thought is some sort of ignition problem, but I'm not sure where to look. I have an MSD distributor, and the rotor and cap look good. MSD 6 box. I have a Crane coil (installed by the PO) but don't know if I should just replace that to see what happens, or keep looking elsewhere. I have noticed at cruise, that I think I feel an occasional stutter, like a very intermittent miss, but it might be nothing more than road bumps I'm feeling. If any of you have any suggestions, I'd sure appreciate hearing them. This is at the least embarrassing, and at the worst, potentially deadly.
