Mallory Hyfire Ignition problem

Update, got the box back from its 2nd warranty trip, the packing slip said that they replaced a transistor, which seemed promising. Mounted the box, did the wiring, dropped the distributor in and the car ran for all of five seconds before shutting off, same exact symptoms as before. I've given up on talking to MSD, going to call Summit Racing tomorrow and see if I can get anything to happen in terms of refund
