The pickit is only capable of supplying a limited amount of current to the circuit when it is powering the circuit (depends on USB port power output i think). If you are supplying power from the pickit then maybe the un-powered DC-DC is loading the pickit beyond its current capacity?
When I load the program, with the controller in the truck, using the Pickit 3, Mplab cannot see the chip unless the controller power is on. I just thought that was the way you were supposed to do it.
