Buick LeSabre Wont Start In Hot Weather

I have a '86 buick lasabre. Lately, it wont start in hot weather or it will die if its been running a while. After letting the car sit it will start back up and run and the problem will repeat itself. In the last year I've had a mechanic replace the following: Fuel pump/filter, Ignition Modulator, Fuel Pressure Regulator, battery, starter (due to various reasons, related and unrelated.) It becoming a very troublesome vehicle. Any suggestions on whats my next step.

I agree it is the crankshaft sensor. My 97 does the same thing. if you take it to the shop they probably wont get the car to fail (stall) when they test it. If it stalls on you ,locate the sensor on your car, spray some cool water on the sensor. If it starts back up after a few minutes, you know the sensor is not operating correctly.
It could be the fuel pump or the fuel filter that might be clogged but I bet its is the sensor.
