So there's an issue with the dodge breaking down under load, seems worse on cruise control on an incline.
Engaging the Tow/Haul when it's breaking down does help slightly but doesn't totally eradicate it..
I thought fuel pump,fuel filter at first, not having changed or worked on before I'm hesitant to go down this road first, so the easy fixes for spark include coils, plugs and leads but after that I'm at a bit of a loss.
Does this sound familiar to anyone ?, if so I'd be keen to hear your findings.
