2004 I35 Transmission is Slipping into neutral

I have a 2004 Infinity I35 that feels like it is slipping into neutral even though the car is in drive. All the trackion control lights and AT transmission light go on. If i press the pedal the car revs and goes no where. If i turn the car off and turn it back on it drives fine. I heard the infinity autos are having a lot of problems with the transmissions on the SUVs FX? Any ideas?

I have a 2004 Infinity...Any ideas?
