keep burning out dist. cap and rotor

I have a 1994 GMC 2500 4x4 V-8 that every month or so(2500 mles)
the distributor cap and rotor burn out. What can be causing this
to happen?? I have new plugs and wires in.

dist cap and rotor

the rotor gets black on the contact points as well as the contact
points in the cap, the center point in the cap gets really black
I start to have trouble with acceleration and engine misses so
every time this happens I change the cap and rotor and eveything goes great again for another month.

side to side.

Switch to Delco parts for one run. It may solve the problem.
