Have you checked the function of the control pressure regulator? The  
only part of the fuel system that adjusts mixture as a function of  
temperature. It's perfectly feasible, given it's an electro-mechanical  
device, that it doesn't behave as it should on cool down, leaving the  
mixture appropriate to a hot engine when the engine is just warm.

You need to get a fuel pressure gauge on your car to actually observe  
the primary and control pressures in order to understand what's going  
on. Who knows, maybe it's an ignition problem (eg the connectors on  
the ballast resistors and coil - that's another favourite for this  
sort of problem).
