In most cases, what you are describing is the filter drawing debris and starving the transmission for fluid, when you let it sit, the debris will fall back into the pan (gravity) and allow the line pressure to return to normal and you can drive the vehicle. I have seen some Infiniti/Nissan automatics with those symptoms. Another note, I have seen cases where you can flush the trans. after this concern, as Q-45 tech noted, and the vehicle be fine. I have opened up and inspected a trans with this condition, and all the clutch packs, brake band were in good condition.(But where did the debris come from?????). The lock up clutch inside the torque converter has a lining, in rare instances, that material is what will restrict the flow of fluid by getting into the filter. I don't know of any electrical item, whether it be a line pressure or shift solenoid, TCM (trans control module) that will allow a complete no pull condition. In most cases, the vehicle would go into fail-safe(limp home mode), in return will only allow the trans to operate in third gear. I would suggest a complete flushing of the trans, new fluid along with the BG+ additive and take it from there.
