This usually happens when it rains but it been happening more often rain or shine or at night.

I think theres a short somwhere because I cant have my radio,headlights,ac/heat/defrost,windshield wipers,Etc. and when all that stuff is on everything shuts off and my head lights go to high beams and everything stays off for about 45 mins and then it resets and everything works again and I dont have an idea whats goin on......any ideas would be helpful
