I know. It’s an M body but. Issues. Help.

So I know it’s not an abody. But this is my go too lol. Taking the lean burn off of my 86 fit have. I’ve put on a brand new 2bbl none electric control ditched the distributor and put in a Chrysler electronic ignition and vacuum adv distributor. It fired right up. Ran for 20-30 seconds like before. Then died. The lines the the smog canister are just plugged on the carb Just to get it started. New cap. Rotor. Plugs. Fuel pump. It’s like something is just shutting it off. Then hard start. Usually won’t start. Any suggestions.
You running a ballast resistor?
