Engine Stalls when temperature reaches 210 degrees

I have a 1999 Pontiac Grand Am SE, 168,200 miles, V6 engine. When you start the engine, it runs smooth until the temperature reaches 210 degrees, then it will stall out. I have changed all the spark plugs & wires and a few sensors. I have taken it in for a diagnostic check and the meter reports nothing. Just yesterday, the check engine soon light came on. What do you suppose it could be?

Looks like at least three of us have a similar issue. See also "stalls from a dead run" and "dies on off ramp". All V-6 pontiacs with about 150K. That don't like heat. Kinda like the blower resistor thing I guess. I'll let you know if I get any help with mine.

I think that may be a little hot for a v6, check to make sure that your electric fan is working, my wife had a VW that would run fine until it got hot and it turned out to be the fan after hundreds of dollars in tows and repairs, if you only drive short distance or on the highway it will probably stay cool enough not to stall but in traffic or at lights you may be overheating, just some symptoms there, it is pretty easy to see if the fan is working just pop the hood and let the car run and look but don't touch the fan. If it is not working get it looked at ASAP the aluminum heads in that small engine can and will warp very easy from excessive overheating

Get ahold of your local pontiac dealer. They have a recall going that consist of no starting/dying. The problem is the ignition circut overheats. They will install a relay kit to repair. What that does I have no idea but it seems to be repairing problem.
