95 Intrepid ES Stalling Problem, Please Assist

Hi all, Im new here. I have a 1995 Intrepid ES with a 3.3L V6. I drove it cross country recently, and it was fine for a month or two, with no issues, until about a few weeks ago. I started having problems with it stalling occasionally. I will drive around and its fine, but then, out of the blue, such as at a stoplight, the rpm's go up, then drop and stall the car. I thought it could have been the Throttle Position Sensor, so I changed it out, and it seemed to help, with ALOT less stalling. It then started coming back. It doesnt do it all the time, and it could be days apart if it does it. Its not an everyday thing, but I was wondering, does it sound like its the Fuel Pump? I just changed out the plugs, wires, tranny filter, oil, and air filter. I didnt change out the fuel filter yet, but I was thinking if it was clogged, wouldnt it just stall out ALL the time, not so much apart in time?? There are no engine codes coming up or anything, but I am worried it might be the fuel pump. Any advice would be greatly appreciated.

I've got a 94 with a 3.3 that also stalls out here and there. Mine loses spark temporarily and I've narrowed it down to a bad wire, just not sure which one yet. When your car dies, check to see if you have spark and pulse at the injectors. If you have both check your fuel pressure, if one or the other is missing, check wires back to the computer, and ultimately the cam and crank sensor. Also, check your asd (automatic shut down) relay in the underhood fuse compartment.
