stalling issues

I have a 76 Cordoba with 400. Recently after perfect starting - the car runs for about 2 minutes and then stalls abruptly. Will not restart - just cranks. After overnight - cars starts perfectly and the same - stalls and will not restart until next day. I seem to be getting plenty of fuel after the stall. I checked for resistance and continuity after cool down and - all okay. The other day, I started it and it ran perfect for all the time until I turned off. I pulled the ECU off and noticed two small areas of leaking on the back side. I am thinking some type of breakdown of a capacitor or something causing the melting and ultimate leaking. Your thoughts would be appreciated. THANX
