You're really gave us a tuffy. Maybe some more info, miss as in only under load or even at idle.
That OBD1 isn't very helpful, now if it was an OBD2 you may have gotten some good info out of it.
Now for the guessing, if everything was running great then a full tank and you get an issue then maybe the fuel filter is clogged from that station. More than likely it was just timing of the fill up with something that broke on the engine.
Again when does it miss, sounds like it doesn't take much to get it to run poorly.
One more guess, what type of oil are you running?
Flat tappet engine.
