What would cause a squealing noise under the hood of an 2003 Ford F250 when the gas pedal is pushed?

A loose belt is the most likely culprit, when you press on the gas all of a sudden the engine will respond quickly but a belt driven component like the alternator will give resistance thus causing the squeal.
