If you hear air leaking when actuating the trunk with the key or one of the switches, then your latch is most likely leaking air (which the PSE pump will eventually shut off and disable). You shouldn't be able to hear any air leaking with it working properly. Also check the wiring around the trunk hinges to make sure one or more of them aren't broken.
