Answer
Chad,

I've been considering your question from a couple angles...first, I don't have a 944 so I'm not sure what post you are referring to.

Second, as for your no-start situation, I'm not at all convinced a computer, installed in the stock position, would be that affected by heat.  Normally, when the engine cools and then the starting is better means the heat is negatively affecting the starting process, not necessarily the computer itself.  

The place to start is to consider the possibility that the engine heat is warming up the nearby wiring (especially the wires at and from the starter...any heat adds to the wire's resistance and any resistance reduces the voltage you'd expect to be there.  As soon as the wiring cools and the resistance eases, the starter will work.

I'd suggest checking the wiring rather than the computer.  Give it a try.
