Engine Stall and Misfire power cut off on acceleration

Car idles smoothly then suddenly shuts off occasionally after about 1 minute. Car cuts out for a split second on acceleration when about 1,500-2,200 rpm. At the same time dash lights flash for a split second when the car cuts out. It consistently does this only in this acceleration load period under this RPM figure. Rides smoothly at 60-70 miles/hour. No codes. I tried swapping out ign coils, mass air sensor, throttle pos sensor, crank sensor, cam pos sensor. Checked all wires under hood and ECU connections and cleaned. Swapped out ignition solenoids in engine bay
