weird cutting out problem

ok checked spark plugs and come to found out, passenger side bank was running lean so i yanked the carb off and rebuilt it, and ran fatter jets but didnt replace the spark plugs, plugs looked ok, checked the distributor cap and rotor and it was alittle crappy but cleaned it up. Drove the car for 30 minutes and acted up again, pulled into auto zone, got a new cap and rotor, installed it and now it didnt wana start. Decided to check the ignition so i straight wired the wires going to the ballast and **** started right up. so got a ballast resistor at azone and went on my way. 2 fkn hours later it does it again, this time cuts out even in neutral, then dies at a stop light, crank it over alot and still didnt run, move it overpulled it over wondering wtf is going on, let it sit and tried to start it and started up and ran good after that! The only thing i havent checked was the fuel delivery. Ill check the lines to see if something isnt pluging up, Fuel filter doesnt look dirty but ill check that also
