Check distributor shaft bearings
I had similar problem for several years. Everyone suggesting I do things to cooling system and catalytic converter. Dumped a lot of money chasing the problem. As last ditch effort took truck to a private mechanic who quickly found the the distributor shaft bearings were shot (bronze journal bearings). He replaced and I've never had a problem since. Apparently the timing was firing randomly +/-10°.
