I have the same setup as OP, an 03 Dodge and P3 controller and have experienced the same issue and it was plug connector.
A careful cleaning took care of it.
Love the disk brake setup ! Best thing I did for the camper by far.

At first, I also figured the problem might be in my truck connector or the trailer connector. I had recently changed my connection set up to the EZ Connector product, so I immediately suspected it as the cause. I changed back to the original type cable and connectors, and triple checked the connections under the truck and at the pinbox all the way to the pump. I also have a trailer emulator device which showed the truck end of things to be good.
That's when I tried Ron's suggestion to add a 12v light across the wires I mentioned previously, and then the problem was gone. So he shipped me the resistor(the light would not be a durable enough solution).
So, in conclusion, if you experience the problem, it could be a connection, or it could be the need for the resistor. Ron said that the problem does not happen very often. I was just unlucky.
I agree.....the disk brakes are great.
