Is it an programmable/adjustable LVC? If it is, that may be the issue.

Try using profile 2 on the ESC (assuming you have the stock EVX), this eliminates reverse and makes you only have brakes. This should fix the problem.

The issue is that the EVX goes straight into reverse once the motors slow down enough, so any extended brake signal results in reverse.

I have a similar problem with my 18T. My Spektrum Receiver's Failsafe is set to brake slightly, but since it usually takes a second or two to kick in, its enough delay for the Mamba ESC to unlock reverse (its programmed to unlock reverse after the trigger has been in neutral or brake position for two seconds - must be returned to neutral if it was in brake). This usually throws it into a reverse spasm.

Fortunately, I've never lost signal with Spektrum, but I am going to have to re-program the ESC or reset the failsafe to solve the problem (either lock out reverse or set failsafe to neutral).

For now, I dont have to worry since I cut my antenna in half...I'm going to get a new one soon and solder it on.
