OK, by craft sensor, do you mean crank shaft sensor? I would like to also add that this happened to me such a long time ago with my '90 2.5 lumina, that I almost forgot about it, but one time, I was driving, and the thing would run good untill I accellerated above 50 miles an hour. Then when I came to a stop, would idle great, but then when I went to go, I gave it gas, and it died, and it started right back up, idled good, I gave it gas, it died again, started, died, started, died. This kept going on and on, till I could accellerate slow enough to keep it from dying. Well, I drove it to the nearest mechanic and explained everything. He popped the hood, got out a wrench, and I believe pulled a fuse in a fuse box on the passenger side of the car, towards the front of it, I'm not sure anymore, he also told me that he believed it to be the "Overdrive Converter". I have never heard anything like this before, but he said he disconnected it. I got in, drove it home perfectally, no stalling, nothing, although I did notice I had no overdrive, coincodence?. When I got home, I got to my mechanic, and said, the overdrive converter is bad, he replaced it and the problem was solved. The only problem is that this happened so long ago, and I never saw the part, or where it came from, so I have no idea what one is. Or where to start looking for one, but if your problem seems anything like mine, you might want to check that fusebox for a fuse for something that sounds like an overdrive converter, and pull it, and run the car to see if anything has changed. Good luck.
