herky jerky (fuel pump???)

I own a 01 9-5 LPT with 135K miles. Recently, it began to experience an occasional (still rare) sudden jerk when driving (only) at highway speeds. It happens on steady speed or upon slight accel (never on strong accel or decel). The car jerks suddenly, almost like some kind mechanical interruption. It can be one or perhaps a couple of jerks, but then perhaps miles and miles more before repeat. The problem seems like it could be fuel supply, but it recovers almost instantly, with not time to look at tach, boost, etc. Neither the engine or tranny trouble lights come on. Looking at posts so far I see these possibilites: fuel pump, fuel filter, turbo bypass valve (?), torque converter (except, no codes). DIC was replaced at about 60K. Ideas/suggestions welcome
