dx2.0 tx/rx acting up

[Big-Bus7]

Well i have a this problem of my dx2.0 tx/rx acting up for about a month. In my slash i am running a dx2.0 radio system and when i give it throttle or at any time it seems as thought the slash is cutting out or losing power. Like when i try to get some speed up for a jump the throttle cuts out, completley or just half way, and goes back in, same when i give it throttle sometimes i go to floor it and it is like it is in training mode. It is just that the car speed is so unpredictible at any time the radio could work right or bomb out, and i spent 130 on a 2.4 system that is like half a year old. I know it is not the car because the stock radio works alot better than the dx2.0 does, and i have checked things like the radio wire, batts, synchronized the transmitter to the car, and much more.
HELP ME!

Have you tried resetting your EPA for throttle? I have never seen a DX radio do that. I did have one receiver that crapped out on me due to a cold solder joint on the antenna. I popped it open and re-soldered the antenna wire and no problems since.

Type of motor & ESC? Brushed or brushless?
