Start by running a computer diagnostic. That can tell you a lot. If you get nothing from the diagnostic the problem is most likely related to fuel delivery. But the computer diagnostic is first.
Then check fuel pressure. There should be a fuel pressure test port. Make sure the pressure is up where it belongs.
If all of the above test out, run a compression test. Worn engines will often loose compression and that can result in loss of power. GM used a good engine in the 94's and if properly maintained they last a long time.
That should be enough information to get you some good ideas of what's going on.
