When I had that problem it turned out to be a bad battery. You should have them load tested. Also, be sure connections are good. I'll bet that's your problem since everything else appears to be working OK.
I was going through the same issue with my rig, but my voltage would stay at only 11.3 or less. Here is what fixed my issue. All terminals cleaned and tight, also

Reinstall all cables before removing keys from pocket.
After i did the battery trick i have been up and running like a champ. Above quote was from a thread i had made about odd voltage issue. Hope this helps you out also
