If the car is turbocharged, it could be the turbo charge controller. It's a small piece attached to the air intake box for an s60. These are known to go out on the s60 and are usually covered under a Volvo recall for that part.
It can also be the MAP Sensor. If it goes defective or the o-rings that seal it to the air intake pipe harden, it will cause the same problem.
To separate the issues, drive up a hill quickly, forcing the turbocharge to engage. If you feel intermittent power loss and gain, it is likely the turbo charge controller. If you notice the engine having trouble accelerating from a stop (vibrating or jerking hard) or dying when accelerating from a stop, your MAP sensor is to blame. Either part only costs about $80-90 and can be swapped out in seconds. They're in the engine compartment and very accessible, only held on by clips (and tubes for the turbo charge controller). Definitely call the Volvo shop and see if yours is covered by the recall. Free is always better.

How does a guitar make a noise?
Acoustic: The string vibrates - this causes the sounding board of the guitar to vibrate at the same frequency (note). The velocity of a wave through the soundboard is higher than that of the string, so the soundboard causes sounds much louder than the strings. Electric: The string vibrates, which disrupts the magnetic field of the pickups. Whatever frequency a string vibrates at causes a different magnetic flux. An electrical current can be induced by a change in magnetic flux. This current is sent to an amp, which produces the sound.
