My car runs good when it's cold but stalls once it warms up? ... In this situation, you can usually re-start the engine once it has hada chance to cool back ... it'll fill-up and exits fuel right up and out the vent tube which dumps it down the middle of ...
this could be a bad fuel pump that has a problem from sitting over night or when it cools down enough.the armature in the pump may be worn and when its cold it has a hard time turning the pump because of it being worn and when it gets warmed up enough the clearance is closer than when cold and works fine.
Symptoms are indicative of a partially broken wire somewhere, the cold increases the resistance in the wires and if they aren't working at 100% to start with, will cause your problem. I think you are on the right track, I would replace any high tension parts not already new then start looking for wires showing a high resistance. Check and clean ( with contact cleaner aerosol ) any and all electrical plugs in your ignition system. I would try drying out your computer and packing around it with silica gel to keep it dry. Good luck
heat related issues usually fuel blockage or electrical resistance to ignitors...run on indicates fuel issues at pressure head not shuttign off fuel.. so check there first...also many related engine management sensors are related to fuel dilvery so get code checked and computer tested/.... good luck
