sounds like the in tank fuel pump. since car is RWD it uses saddle style tank. One pump shoots gas from one side of the tank to the other. That pump is probably failing.
I thought It might be the pump, but why not fail completely. Unaware of the tank design as it may play a part in it's habits.
What's the gas gauge say when this happens?
Not sure of the guage reading, As I said I was not in the car when this has occured. She just indicated it was @ 120mi till empty on fuel center. My wife only looks at that as her gauge to get gas......
