Car stalling out when driven for about 15 minutes

I have read through all 26 pages of alero threads and am in need of some advice. My car stalled out on the highway about 6 months ago. It did if five times and it hadn't done it for a while until last month. It did it again except this time it wouldn't start. Towed it home and the next day i got a new battery. It still wouldn't turn over so we changed the fuel filter. After we did this it started up and ran fine for about 2 weeks. Now it is doing the same thing. The car runs great cold but as soon as the engine heats up it stalls out. I have seen the trac off light come one a few time right before it stalls don't know if that means anything. So far i have changed the plugs, coil pack and the fuel filter. So after much research i have come to the conclusion that i either have a bad ignition module or fuel pump. I can hear the fuel pump regulate when i start the car so don't know if that means it works or not. It never stalls cold so why would it stall hot if it was the ignition module wouldn't it stall hot or cold. Any help would be great Joe. P.S. could it be the CKPS or the fuel strainer those were also a couple of other possibilites?

These are classic Crank Position Sensor symptoms. Earlier you were experiencing the first signs now it is to the point where the sensor fails when it gets hot. Change it out and the problem should go away.
