viggen hesitation

I have a 2000 9-3 viggen with 90,500 miles on it.
Yesterday, after about 15 minutes of driving, the car started to hesitate mildly. As the drive went on, it got worse, and it felt like the engine was nearly turning off & on. Eventually, I noticed that the turbo gauge was fluctuating in correspondence with the hesitations.
There did not seem to be a strong pattern other than the correspondence of the boost gauge & the hesitation - the RPM were continuous, it happened at varying speeds from 35 - 85, varying gears from 2nd to 5th, various rates of acceleration. Basically, my foot is constant on the gas pedal, yet the turbo gauge needle is slightly moving and happening at the same time the hesitation is felt. I hope I described this fine enough. There's no CEL.
Any ideas of what might be wrong?
Thanks for the help!!
