Runs fine cold, but after about 30 minutes of driving the engine starts sputtering and doesn't want to accelerate. What could be the cause?

May be running rich, that is often what happens when runs well cold then when warmed up begins to do what you describe. MAF, MAP, several things. I see 1995 but it MAYBE is OBDII. If it is, a scan will help. Live long and prosper.
