What's the mileage, spark plugs replaced yet?

In addition to checking the ignition system, it could also be a sensor. Have they checked your throttle position sensor voltages?

I had this happen to me in my 14 Maxima sv. The difference was while I was driving I suddenly got a sputter and sudden loss of power like my tranny was going out. It turns out nissan has some kind of fail safe with the mass air flow sensor, when it goes bad it shuts the motor down to avoid damages. if you do need one try carID, partsgeek, or nissan oem part site. It will take minutes to replace, hope this helps.
