94 PA Turns Off When Hot Outside

so spring is almost here and the temp. outside is rising here in Houston. Whenever it gets around 85 or higher my car runs horrible and while im driving it will turn of on me constantly. The car will start back up. This was happeining last year also but during winter my car has been runing with power and has not turned off on me till now. Please Help! please!

Have the ignition control module (ICM) tested first, and if it checks ok, you may want to consider replacing the crank position sensor.

will let you know thanks.
