Sounds like your batteries might have a bad cell. Mine did that to when i had the hpi efirestorm flux.

It could be your speedcontroller is set for Lipos. A lipo will be considered almost empty on 3,3 for each cell or a little more volt under load. I could be the NiMH batteries drop to around that level, and the speedcontrollers shuts the car down.

What speed control are you running. If you are running the 14 volt titans I'm assuming its the orange evx if so you can run bigger batteries as long as you stick with 2 6 cell nimh. If you have the money to spend I would recommend getting the new evx2 esc that is water proof and can handle 16.8 volts. It also has lvd so you can run lipos if you have them.
