Need a lil BL help

Wut's up, I have been having some problems recently with my BK 9920 controller and fiego 7xl motor. I am running (2) 7 cell packs in series with an outside rx battery.

The other day it started like glitching when I would pull the throttle. It would like cogg a little and make alot of beeps like I was programming it but I wasn't, after inspecting it I found out that one of my solders on the connectors had broken loose and so after fixing that the problem went away. Well now it seems to be back again as I was driving it just now. None of the connections are loose that I could see and so I pulled the red jumper and everything out of the controller so that I could see if that would reset it, but to no avail. So now I come to you the super-wise brushless guru's.

Any help would be greatly appreciated. O ya this setup is in my custom hellfire. I have had more problems with electronics in this truck than all my other trucks put together.

thanks again

BIG D
