Ready-to-Run Distributor and Blaster Coil Issue

Hey guys, so the other day the Barracuda died on me. Had it towed to a local shop I've used before and they informed me that my coil, rotor, and distributor cap needed to be replaced. Then they told me they wanted $300 to fix it.
No thanks, I'll do it myself.

I had been contemplating an upgrade in the future, so I figured there's no time like the present, and decided to go ahead and order some new parts.
Parts came in yesterday and I took to installing them. I got the Summit brand Ready to Run distributor and MSD Blaster 2 Coil. Got the distributor dropped in, bypassed the ballast resistor per the install instructions, and hooked up the coil. I called MSD to confirm that I could hook the electric choke back to the positive side of the coil where it came off, and they said that was just fine.

So to the issue....

At first I had the dizzy 180 degrees out, pulled it, dropped it back in and she started right up. Adjusted the timing and got it running pretty well. let it idle to temp, then went for a drive. About 3 miles down the road, all of the sudden she cut off. I pulled over and now I can't get her to start back up....

So....what did i break?
