96 Cierra stalling problem

[wreckdiver]

I have a 96 3.1 Cierra. After it warms up, and seems only when the temp outside is hot, it stalls while driving. First it goes to a rough idle, then it stalls. I shut the key off for about 15 seconds, then it starts back up and runs fine, untill it does it again. The hotter it is outside, the more it does it. I changed the fuel filter but no luck. I was told maybe the crank position censer or ignition module. Any thoughts?

Welcome to AF, you need to check fuel pressure and spark when this happens, then we can pin it down better.
