[s-cars] Light throttle slit-second hiccup

[Wylie Bean]

Getting this a little more often..usually under very light throttle load @ cruising speeds ~60-65 mph. Feels electrical...like someone's pulling the plug or flipping a switch then putting it back....not a stumble like a miss...more like a momentary total shutdown but it never gets there before catching and resuming normal running.  Thinking loose ground....?  Bad ignition switch? Haven't looked, is there a throttle switch on the throttle body?    Other possible culprits?
