SOURCE: wont stay runnin
It sounds like the same problem I have on occasion with my 1994 GMC Safari van. You need to check your AIC valve ( air intake control) it may be bottomed out wich is the reason it starts but will not stay running. Now I also have another possilbe solution ckeck to see if your catlist converter is not plugged . Not shure why but these are some of the solutions that I have for what happenes to my van . Hope this info can be of some help.

Engine stall or RPM fluctuates
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
