If you tested endstops with printed flags, not all materials block IR well and perhaps the printed flags dont do a good job at blocking either. Can you clarify if you tested with multiple materials,...

Perhaps the xbox psu is not able to provide all the power and it just shuts down in a protection mode. You could try use an computer atx psu instead, that could offer more power on 12v line, at least...
