Answer
If your Maxima has a Fuel Pressure Regulator in the system, it is possible that it is malfunctioning, and dumping excess Fuel into system. You may also have a cracked Spark Plug, but generally that type of problem is not transient in nature. Other than that, I'd recommend scanning the Vehicle Computer for a Fault Code, and see what it turns up.
