I had the exact same problem in my '95 Trep and my 89 Jeep. both times it was my fuel filter. There is no need to remove the tank though. The one I had to replace is on the underbody rail (middle of the car, right hand side if I remember correct). I isn't hard to change, just be careful not to break the quick connect clips holding it on.
Read a manual about de-pressurizing the fuel system or you might get some spillage. (depressurizing is easy to do as well).
One last thing, leave your battery disconnected for about half an hour, to reset the memory,or your car still might not run as well after changing it.
When you drive on the highway, the fuel pressure drops,and the demand is decreased, hence better gas milage on the highway. But when you get off the highway, and have more demand for fuel pressure, if the filter is restricted the car stalls. (that's how a mechanic explained it to me anyhow.)
Hope this helps, but I'm pretty sure that is your problem.
