Is your check engine light coming on? If so, please post what code it is sending. You can have it read for free at Autozone.

\012Generally when a vehicle suddenly has an issue, an electrical component has failed. A common component that fails instantly is one of the ignition coils mounted above the sparkplug. The check engine light code will indicate which cylinder is experiencing a misfire in this case.
\012
\012Another component that goes out instantly is the MAP sensor. Usually the car won't even start when this unit goes out.
\012
\012There are several components that feed signals to the Powertrain Control Module, and any given one of them will cause that unit to alter the performance of the car. Your quickest and least expensive method of finding out what component is defective is to pay for a diagnostic analysis at a reputable garage. Let them identify the problem and then you can gage whether to fix it yourself or not.

My 2007 Nissan sentra starts making a whining noise after driving for roughly 10min. When I accelerate harder the noise gets louder and has a higher pitch. When i let off of the accelerator the noise fades. When I drive around town and not on the interstate it takes longer for the noise to start.
