car cuts off after a short distance of travel on 1990 Toyota Supra

it occurs every day and more frequently now, i would check the coil pack which is brand new to see if it gets fire and it doesnt sometimes, was told that the control unit or module needs replacing. Just want to be sure its nothing else
