Ok here is my issue

I have a 95 Monte carlo with a 3.1 engine. It started overheating but only when i was driving at high speeds. I took it to about 4 mechanics and no one could properly diagnose it. I have had a chemical test done to the radiator to show if emissions are getting into the coolant. That checked out ok. They have overlooked the entire motor and could not find and signs of leakage that would relate to a gasket. There is no coolant getting into the oil at all. I have had the following replaced: Water Pump, Thermostat, Radiator, Fan Relay. I have even hard wired that fan to stay on constantly.

The Radiator was a help but for only about 3 weeks. After that, it began to run rough and stall out on me. Sometimes not starting without pumping the gas, even though its fuel injected. Then it started to redline at lower speeds and is now not drivable. Im not sure where to go from here. Does anyone have a suggestion before I have to resort to the dealer?
