Possible MSD 6AL failure

If you find your problem, remember to post it here and how you fixed it. I have the exact same problem. Car starts then quits. Look under hood, find no obvious problem and then try key again. Sometimes it will fire right up again, sometimes it takes a few tries. This will happen a few times then the car will run perfect for a couple of hours. Frustrating as hell not being able to track down an intermittent problem.
