Ignition Trobuleshooting

New ballast resistor, it started after cranking for about 1-2 minutes. Ran smoothly for 5 minutes. I took the rad cap off to help burp the system and to top off the radiator. As I added water it started to lug and then died. After that there was lots of cranking and it almost fired a couple of times but no dice. Maybe a carb issue? Starting to pull my hair out! I did remove the virus from the computer today so at least I'm not typing from my phone.
