Update... so when I got home today I hoped in the Jeep and drove it to Advanced auto parts. Had them check my battery and my alternator. They both passed with no problem...... however, the thing ran great again , no cranking issue no lights coming on, no bad idle.... I'm gonna drive it more this week and see when it happens again..

In addition, do the negative-battery-post-to-alternator-mounting-screw-mod for a cleaner ground connection. There's a couple of threads on it. Quick and cheap mod to do. Yes, if the JK's circuit loop is compromised (weak battery, bad ground, etc.) then the electronics tend to spazz out.
