My 1997 Town and Country starts and dies until the engine gets hot. Then starts and runs, still stalls at lights. Why?

What is your question?

My 1997 Town and Country has many issues but this constant stalling is unacceptable and unsolvable. It had the typical stalling issue due to instrument cluster solder joints and that has been fixed. It was inspected last year and the EGR and cam sensor were replaced. The stalling began again in ernest. It starts cold and runs fine for 10 seconds to 2 minutes and dies. It restarts runs a few seconds and dies....starts dies, starts dies (harder to start as it gets warm) until the engine gets hot. Then it has to sit and think, I guess for 5-10 minutes then starts and runs fairly well, but stalls at lights. Have to keep "heel and toeing" it to keep it running. Replaced crank sensor, coil pack, plugs and wires, as suggested by scan numbers read by parts store. (Forget that) re-sealed intake manifold and injectors, checked vacuum lines and cleaned the throttle body, and tps. Separated the melted wires to the upper O2 sensor. (makes me wonder about the rest of the wiring) Map sensor seems fine but the signal voltages seem upside down at 1.3 not running and 4.8 in idle. Recent fuel pump and filter, and swapped out fuel pump and asd relays. Also replaced the battery, worn out by restarting. All this and there has been no major change for the good or bad. I've learned from this that codes only point at a condition affecting a part, not necessarily at a bad part and a condition may not throw any codes at all leaving us in the same place we were 40 years ago, but worse. Before I spend another cent or lose all my hair, does anyone have any other suggestions?
