Starts and then dies

Hey guys, I finally got my 408 in my 86 W150 but heres my problem. Right now it'll run on the "start" position but immediately dies in the "run" position. Its been converted from lean-burn to std mopar electonic ign with an orange module, 2 terminal ballast, 2wire dizzy.* Heres what happened, it ran fine for 20 min on break-in, and again for 10min to adjust the valves. After adj the valves, I started to tune (timing/idle/float level/idle mix) at which point it just died like I turned it off. Trying to restart it gave the same symptoms (stat/die) until the point where I had no spark (verified by remotely turning it over with the spark plug 40 thou from the manifold bolt).* So I stole the box (silver) from my 84 parts truck, nothing. I then went to napa and got a new silver box, and vroom it went. So after a 20min drive to see how it runs and a gas-up I came home to push my parts truck into my shop, which involved multiple pulling and pushing attempts. Anyway, just as I start pushing it inside, it started running rough to the point where I couldn't keep it idling. Apon several failed restarts I figured I got a defective box. I exchanged it for a black, and to no surprise it didn't remedy the problem. At this time I forgot about the ballast, so I bypassed it a vroom it went, so I figured it was the ballast all along so I pulled the one from my 84, yet still no runner. I figured coincidentally both box/ball where faulty so I got a new one just to make sure, unfortunately still nothing. I then checked if the blue/yellow "run" wire at the module had voltage, and it does. So at this point I'm stumped and would greatly appreciate any help. *** Much thanks!!!
