The headlights and the dash lights as well as the radio and the interior lights all short out while im driving...after it sits for about a hour or so it just randomly while driving again starts to work.
I just fixed this problem. Check under the hood the pos terminal it will branch of into 2 wire follow the one that turns into 3 wires. There is a fusable link at that joint this just may be your problem easy fix it was mine.

I take it you mean that the radio stops working completely once the headlights are switched on. So if you sit in the car during daylight hours and turn the lights off and on, the radio does the same except the other way round (lights off, radio on). Have I got that right?
It cannot be the fuse because the radio wouldn't work at all if it had blown. The wiring may well be the problem. Something is either shorting or I am thinking that there is not enough power (for whatever reason) to run both lights and radio at the same time, although the battery draw on a radio is relatively low. Is your battery charging correctly? Does it happen if you open all doors and the interior lights operate. Try opening all the doors and turning headlights off and on. Do the interior lights turn off and on like the radio does?
You probably already checked this but the simplest solution is the control used to turn on the interior lights and to dim your dash lights. It is a dimmer switch to the right of your headlight switch. If it is turned all the way down then you would have no dash lights and no headlight chime. Turned all the way up it turns on your interior lights. If this isn't your issue and if no fuses are blown then try to turn the dimmer switch all the way up with your headlights on. If the dash lights come on with the interior lights then your switch is fried and you may have a short in the interior light circuit.
There is a headlight relay and each light is on a different fuse. Then the dash lights are on another fuse. It could be a problem with the headlight switch.
check fuse block for shorts, melting discoloring,on back side of fuse panel around starter relay. loose connection causes fuse block to over heat will need to be replaced.hope this helps.
you have a loose wire or a short somewhere in the dash. Hopefully you can fix without changing the harness out. I'd try some test to try to isolate the problem. with the engine off, and the lights on and radio on, reach under the dash to where your fuses are located and lightly move the wires coming from the fuse box watching and listening for the short. If you cant locate here, move your hand deeper into the dash again lightly mving the wires behind the radio and then the light swtich. good luck of finding this.
Try replacing the headlight switch. Most of your probs should be resolved. The switch being bad will cause a short in the dash and cause alot of weird things. But that switch does control all of which you are describing including the radio, when you turn your headlights on it dims your radio !
possibly the dimmer switch on the floor? happened on my 91 half ton dims didnt work but brights did and then they cut out altogether. a little water goes a long way
