Woah! I have never heard of that happening before! Now your question about the temp, yes, the car will run at about 80*C and the temp will drop on the freeway a little because of the constant cold forced air (ram air) under the hood. Actually, now that I think about it, it might be stalling beacuse the FI isn't metering the correct air/fuel mixture because of the temp. I can't say for sure, just a guess.
