Your 6-in-1 switcher -5V mod cable is feeding all your connected MK boards at the same time. Some say that it is OK but I used another set of relays for the -5V mod of my swither.
My theory is that when all your MK boards are connected to the switcher, the power supply "might" not provide enough juice on the -5V line and shut down due to over-current protection. This might be the reason you only see your setup work for only a few seconds...
Have you tried only the switcher connected, without the PCBs connected?
