i just bought a 1989 warrior and when i turn the key on, it will try to start and then it will suddenly lose all power. if you wait about 2 hours, it will regain power and then as soon as you crank it, it will do the same thing. what could be wrong with it.

 

It may be loosing the ground or power wire. Clean and tighten ALL points where the battery cables and source wires are attached. That would be your starting point. After that, you would have to use a DV/om and pin point where the power break is.
