First thing I would do if I suspected the box would be to rewire it without the box, if it runs fine the box is the problem. I would start to up completely cold and see how it runs if it runs fine, I would put a clear fuel filter in it and take the stuff necessary to wire around the MSD with me and hit the road. From what you described it could also be vapor locking or have a fuel supply problem. It if misses when started cold, go to basic diag, fuel, fire or compression and go from there. Good luck!
Careful, your character's showing!

msd will repair the unit.

Again, make sure your grounds are good. My Sons car would start to break down at 4500 rpm. Simply ran a new ground to the firewall.
MSD boxs do go bad. I have a bad one now. Is it mounted under the hood with all the heat? They last longer interior mounted.

OK, I put a blow dryer on the MSD today, got it pretty toasty, but couldn't duplicate the no start condition. I did duplicate the miss, starting at 2800 RPM, very repeatable. This is all in neutral in the garage. I substituted a different coil, same miss, checked distributor air gap, its fine. I wired up an old stock mopar ecu, miss is gone!
Its got to be the msd box.
I guess I will try to find a new box fast for the show next Sunday. Then send the old back to MSD for their $100 repair. Not the cheapest route I know (tell me about it!) but once I got that back I would have a spare. Never been that much of an MSD fan, now I'm a little less, but willing to give it another try.
I made my own engine harness and its all custom wired for the msd box, and I drilled two holes in firewall to mount the box that I really don't want to be looking at regretting drilling them. In hindsight I should have mounted the box under the dash. Or converted the car back to MP stuff.
