Default MSD 6LS-2 failure

I have an LS2 in my 64 Corvette with a Speed Demon and MSD 6LS-2 setup. I have been having all kinds of running on and erratic running problems. The car still has less than 400 miles since completion, and I went to start it today, and it ran for a few seconds, spattered badly as if running on only 2 cylinders, then quit. I finally decided to pull a couple of spark plugs to confirm that I was getting a spark, and there is no spark. So I am suspicious that the MSD module has failed. Can anyone help me diagnose for sure?

Thanks.

Sounds like you need to pull the box and ship it to MSD. Let them check/repair it.
