Default Check Engine Light On/Off Intermittently

Hi there, I hope you guys can help me with this? Once in awhile while driving at slow speed, my lexus would suddenly stop (meaning the engine die). I shifted to Neutral and start the car again. No problem with starting the car again and able to drive for about 3-4 month before it happen again. I don't recall seeing any check engine light cme one when this happen. This had happen to my Lexus at least 4 time already. For the past 6 month the problem didn't occur again. However, recently, the check engine came on and off interminttently while driving. This this morning, while the car is idling, the check engine come on and off. I start to pay attention when this happen and noticed that when the check engine come on, the car seems like it loosing it power. I hope you guy can provide me some clues. Thanks in advance.

kinda hard to get a code if it comes on and off... try disconnecting the MAF sensor and see if helps.
