Had the car out this evening again. Noticed it once. Scanned the ecu and no codes were present. Doesn't seem to happen at any specific time. It doesn't happen at idle and not under any type of acceleration. Seems to happen just when steadily cruising.

Clutch maybe slippin a lil intermitently,are u sure its engine losing power? Maybe a seizing brake caliper,a number of problems. Does the engine itself lug or do anything unusual when it hesitates?

No, its definitely not a brake siezing or the clutch slipping. My guess is either something to do with spark, or something in the fuel system. I will keep driving for right now and see what it does.

This is making my brain numb.

B6 coil packs suck. It could be a flakey one, but not bad enough tothrow a CEL.
