It could be the ignition module going bad.
You say it only does it when warmed up?
I had an '84 that had the same symptoms, it was a bad ignition moudule and sensor in the dist.

They'll fail in different ways..... many will outright die with no spark at all, until the module cools down, and all of the internals contract back into their original (connected) positions. I have, however, had one to fail in such a way that the truck just started dropping cylinders, seemingly at random (the internal circuitry must have been making borderline contact.) If not the ignition module, you may also check to stator & pickup coil (in the distributor, under the rotor). These will also fail in much the same manner..... Good luck!
