Sounds to me like it's running while auto enricher is on, then quits as engine warms and enricher closes. This would mean plugged idle jet or idle jet passages. This would also explain why it dies when you try to open throttle while it's running...You're giving it any extra shot of air, and it is still only receiving gas supplied by enricher. When you cleaned the carb, did you remove the jet and spray cleaner through to verify that the pathway to the tiny little holes located in front of the butterfly are open?

Before I spent any money on electrical components, I'd make sure fuel system was right. Fuel delivery lines, vac lines, and fuel filter, should be replaced...especially if they are OEM, black, rubber hoses. Ethanol laced gas turns these to mush from the inside out, over time... I would also pull the valve cover off, check clearances, and adjust them if needed.
