Default Need Help With CEL Issues

I have a 2009 Ultra with FM 107 kit and FM Level B CNC heads. Just recently, when firing her up I am having a strange CEL issue. I turn on the ignition and the CEL lights per normal for about 3-4 seconds and then goes out, as normal. Once fired up though, the CEL comes back on for approximately 7-8 seconds and then goes out. It doesn't appear to be storing any codes and the bike runs quite normally when riding. Is there anything I can check or look into using a Power Commander V that might give me some insight as to what is causing this?

In addition, although I am getting no codes, I am also getting the "no response" from the ECU segment of the diagnostics routine. Clearly I have an ECU but it is plugged into a PC V. Anyone have any idea what's going on or the best way to re-establish communications?

I'd try taking off the power commander to see if it still happens.
