HID Headlamp turns on then off

I have a 2013 Enclave. The passenger HID lamp goes on initially for about 20 seconds and then turns off. I have replaced the headlamp. Same problem. I have moved the ballasts from one side to the other. Same problem. No problems with Driver side. Turning headlight switch on and off turns both lights back on, but only for about 30 seconds on the passenger side. I have looked at the wiring schematic and only see 1 splice from the low beam relay to both headlights, so probably not the relay.

Help..Any ideas.
