You really have to make sure you are getting spark before you decide it is a fuel problem. Since you said the plug swap won't get you started you have to consider that it may not be a fuel system problem. I would inspect the primary ignition system including the ballast resistors, the wiring and connections to the starter, and the bypass relay. It should be easy to troubleshoot as it seems to be consistant ie it always happens when it is hot. The car should not backfire AT ALL! I would suspect bad ignition wires, cap, and rotor. You might also have to adjust the intake and exhaust valves. I think at this point if you haven't done it and you don't know when it was last done (if ever) you should do a complete tune-up replacing the secondary ignition system parts and cleaning the fuel injectors. Finish by replacing the injector seals, air filter, and fixing all the vacuum leaks before setting the mixture on an analyzer. You might want to also make sure that you are getting power (when the ignition is on) at the plug going to the control valve. A problem with the power on that plug would keep the plug swap trick from working and make the car hard to warm up.
