Sounds like something more to me.
There's only one o2 sensor on the 93. And that controls fuel trim.
So even if it was broken it'd think it was running lean and throw in extra fuel into the engine.
That'd cause it to possibly run like a bag of shit, because there's more fuel than air but you'd notice with lots of gas like smell from the tail pipe.
Sounds like its stalling on load, more so than it is related to hills. Try checking filter (clogged, dented), iac valve (sticky), the main relay (buggered), plugs (condition), wire (condition) and if none that works check the ignitor (if no good it'll stall out and you have to wait for a bit to start it up again)(inside the distributor).
