Ran good at sea level, Northern Califonia coast where dead of summer temps were never more than 80 degrees, if that, plus lots of cool humidity off ocean. Moved to Colorado over summer at 5,500 feet and 100 degrees, it ran for 5 mins (including start-up) and died while driving, most often when i started boosting real good, it stumbled and died, wouldn't restart for many hours or until middle of night when ambient temp decreases to 80 degrees. then drove for 10 mins and died again. Left it at supermarket and got up at dawn next day when temp is coolest and drove another 15 minutes home with it. Brought to two mechanics. Stumped all my mechanics and they changed out fuel pump, AIC, AMM, 02 sensor, etc. until they said maybe the distributer is bad (I assumed hall sensor overload due to heat). Car has 200K, Distributers don't last forever, maybe another component of/in the distributer is faulty, not Hall sensor? Faulty distributer wiring? But why does car perform better and less prone to die in colder weather? Not talking about better boost and all that in winter months, I just mean it doen't want to hiccup and die so quickly now that temps are way down in Colorado to 60 during day and 40 at night... But if I really get on it and boost alot, it'll shut down again.
