    Did you use the same controller for both trucks? If you using a fishstick it could be either the computer chip in the control or the wiring in the control.

    Loose ground on the truck side or corrosion in the truck side grill plug. Checking all grounds is easy enough. To check the grill connector have someone function the controller while twisting the grill connector with both hands. If doing so affects it then you know the connector has issues inside.

    Be careful of blade movement while doing so.
