Light acceleration at cruise stumble

Hello all,
Holley 750 HP body Dp. Quick lean spike while at a 40 mph cruise at 2000 rpm or so, on light acceleration only. Not sustained. Only when I slightly speed up to keep up with traffic. AFR gauge shows a quick lean spike, as quick stumble, recovers rich quickly, then stabilizes. Happens in about a second. All other conditions are perfect. Wot takeoff from idle is perfect. I have tried everything. Too much to list. This is very annoying. Any help?
