Deano,

With electrical problems, there are a few roads to take to troubleshoot it.

Usually, start from the source, or the battery. Check all connections, the ignition switch, ballest resistor (if it has one), fuse block, you get the picture.

If you can't find any intermittent connections, then sending the box back for a look see by MSD may be the answer.

I've seen many poor crimp connections in my time that were very intermittent and drove the owners crazy. Don't be afraid to pull on the wires to see that they are tightly crimped. The best thing to do would be to solder any crimped connections.

Good luck tracing this gremlin ....
