I have the same truck and sounds like the same problem. I did call Redcat and they told me it sounded like I needed to bind my transmitter with the truck, because it lost contact with the receiver. I tried but found out my receiver on the truck was dead as no light came on when trying to bind. Don't do what I did, I was told to look for the light on the receiver, when all the time I was looking at the light on the ESC. I couldn't see the light on the receiver because it was dead. Redcat went good and a replacement is on it's way. BTW, I only had mine for a week, only charged the battery twice. Hope this helps.
