Hey guys. 
Out of no-where my truck has no power with the key in the on position.  Like wipers dont work, the starter doesnt start.  But I can still turn the headlights on and everything that is NOT powered by the ignition system.
If I jump power from my battery to the little distribution block on the firewall with 2 studs (2 wires on one stud) (I believe one is Distributor and the other is to fuse box) It works great.  I can start the truck and use everything.  I have replaced the fuseable link with an ATC fuse holder now, solder and shrink wrapped.  
Any ideas where I should be looking?  Thanks guys.
