My stereo shuts off while driving in everyday in past two weeks

Hi, I’ve got a Pioneer AVH-2550NEX stereo about two years now that has been running great and then within the last two weeks I’ve noticed while driving that the stereo shuts off completely while driving not at any specific minute. I cannot get it to turn back on until I put the truck in park and turn the vehicle off. As soon as I do before the keys come out of ignition, the stereo will turn back on and stay on anywhere from seconds to a minute, or until I open my driver side door. Any help would be much appreciated.
