Trouble with MGM 22418 - HELP!!!

I am having the LVC problem that others have written about. In this case I really don't believe my batteries are a problem. Here is the setup:

MGM22418
NEU 1521/1Y
FlightPower 6S 25C 5000mah

I had previously setup the controller using the "Reduce RPM" Low voltage cutoff setting. I decided that I would rather have the protection of the "cut off" mode. I also noticed when I was checking the data after a run that the value "Current in full throttle [A]" never had a value. I assume that that value is never present because the controller never actually goes to full throttle. The truck seems to run good when in the reduce RPM mode but cuts off in "cut off" mode. I have previously run autotune. I thought maybe I had a bad solder joint on my Deans so I re-soldered them all.

Does anyone have any idea what is going on. My battery is pretty good, everyone seems to have good luck with this FlightPower. Connections are good. I have played with lower acceleration settings with no luck. Ideas?
