So I let it sit on with the regular PSU for a while and it did freeze at one point. It was about 1-2 hrs before it frooze. I'm not sure I didn't watch the whole time.
Then i switched the jumper to usb power and dis-connected the PSU. I let it sit for several hours and it didn't freeze. Im still not sure that the ground problem is the answer but how do you eliminate it as a possibility? Both plugs are on the same circuit so i feel like grounding the grounds is a little redundant, but maybe not? should i wire the building ground to the negative on the reprap?
