#3 MMM not dead YET, but something VERY wrong!

[JaySki]

So I installed the latest MMM, hooked it all up and was cruising it around the basement. Was running fine.. obviously.. nothing high speed.
But then.. something started acting up... at first.. then it got worse...
When you hit the throttle, forward or reverse, it just stutters... It's like it isn;t sure which direction to go? Does it in both forward and reverse. Tried disconnecting the batts and resetting... Same. Tried another set of batts.. Same. This is very similar to what the previous MMMs did before just stopping.
I am running an e-revo, 1515 1.5d, 4s TrueRc 8A, Novak BEC with red wire cut on the MMM.
Could it be the NEU? I have a medusa, but I have to solder connectors, before I can try to determine if it is the motor.

Anyone with any ideas? I plan to call CC in the AM and talk to them. If this one is half alive, I'd like to let CC look at it before it's dead.
