351W cutting out

I have a 351 Windsor in a '77 LTD with a strange problem. In general it runs fine, but every once in a while the motor will shake for a bit then kill. It will start right back up and the problem won't be there. The shake feels like a miss. The problem is sudden, rare to occur, and goes away when I restart. I've put a new coil on, and the fuel level in the carb is good. The choke is not sticking. I'd say a couple times lately, the engine feels like it has a slight miss when first started in the morning. This shaking then killing problem, however, has occurred when the engine has had time to warm up. I can't think of what could be wrong. Any ideas?

What do the sparkplugs look like? If they are good and the wires are good then check the distributor and duraspark module.

In case this is of later use to someone, I pulled off the ignition module and had it bench tested at Autozone. Their machine runs about 8 or so tests and my module failed all but one. I replaced it, and the engine hasn't killed yet...I would also say the car seems to start easier. Hopefully this fixes my problem and thank you ken75ranger for responding.
