I just tried to print something from Thingiverse and it froze just after laying the first layer of skirt down. It seems to be freezing sooner and sooner each time I try a print.

This time it froze, but the heaters stayed on.

I re-checked all wiring connections under the printer before this print. I also made sure the power/motherboard fans were working whenever the freeze happened. Everything looks good. I'm completely clueless.
