I have a 98 'tour 2.5L V6, 52k miles.

It's not there when I start the engine, but only after about 15 minutes of driving. The pitch seems to go higher as RPMs increase.

I have a high-pitch noise coming from my Duratec, and it's the MAF sensor. If you poke at it quite hard with your finger, the noise stops. Maybe this is the noise you're hearing..
I'm not decided yet if I'll try cleaning the MAF myself - I'm not sure this would fix it. Replacing the sensor is not an option for now, the sucker is like 170$ (Canadian "Monopoly" money)...
