Would need more details to give better advice. But if you have an ignition coil getting week it can cause the engine to stumble when you try to trim the motor. The 12 volts your sending to the trim motor takes alittle power away from the coil causing it to stumble. More details of when the problem happens and what you mean by Popping would help.
