Engine stumble -- very brief

2000 Viggen, 130k miles
At highway cruise, I get an occasional very brief engine stumble. So brief at first I wondered if it was just a road bump.
Has happened about 5 times in past 200 miles.
Feels like maybe a 1 plug misfires, 1 time. Or one bad gulp of fuel.
Fuel tank is near full. Haven't checked the plugs but they're not old.
Seems like a bad plug would cause more consistent problem. Also thinking bad tank of fuel would be more consistently bad.
Could it be the DIC? Or does that typically fail catastrophically?
Ideas? Thanks-
