97 tj cutting out under heavy throttle

Recently had to fix the sending unit on my 97 Tj 2.5. Pump wasn't sealed to the unit properly. Fixed that and it runs better but still cuts out under heavy throttle low rpm. Has new o2 sensors, plugs wires cap and rotor, ignition module, all the throttle body sensors are new. Fuel pump is set up properly now. Have only been able to drive it a couple miles since the fix. Is it cutting out because the ECU is still re-learning or what? Any guidance on this matter will help
