Bad ignition module in the distributor..... was the distributor you took out also HEI? If so what is the reason you swapped it? If it was, and it worked, try pulling the module from the old distributor and putting it in this one. Many parts stores can test the ignition module. I carry a spare in the glove box. I went through a very frustrating period when the engine would just stop running like turning off the key. Finally tracked it to faulty ignition module. Seems like quality control on them has gone down hill. There are many threads on the subject. I’m sure others can chime in on which seem most reliable.
If you do swap the module be sure to put real heat sink paste under it, not dielectric grease.
