A/C and blower motor quit after running 30+ min

[Jason]

Having a strange issue, the ac and blower quit working after the car has been running/ a/c on but it has to be for 30 or 40 min of driving before it quits. The compressor isn't engaged and the blower doesn't run in any of the positions, low, auto, hi, or economy. However, it kicks on in defrost mode, and the compressor kicks in.. Kept driving on the way home and as I was looking around under the hood the compressor engaged and the blower started working. Same thing that happened this morning. Prob took a good 10 min before it started working again. No burnt fuses that I found (and obviously if a fuse was burnt it wouldn't start working again on its own. Is there a breaker in line somewhere that could be getting tripped or getting weak that resets itself?
