For those that were following this post I wanted to post the resolution. Because of the intermittent nature of the bike only during on one cylinder, I thought the problem was electrical. But after doing a lot of part swapping and diagnostics I wasn't getting any change in the symptoms.
I pulled the carbs to see if that could be the issue. I removed the float bowls and found that they were relatively clean. However, the left carb (the side with the malfunction) had a small piece of trash near the main jet. I'm thinking it would fall away from the jet orifice when the bike wasn't running, then get sucked up and plug there opening while running. Thus the intermittent symptoms. Quickly cleaned the carbs and it starts, idles and runs great now.
I've already started working on the rest of the stuff this bike needs to get back on the road. Will post again soon regarding the maintenance and mods I'm working on. Thanks to everyone for your help and suggestions.
