Welcome back:
That sounds like a grounding issue. If it was a fuse, it wouldn't come back on. I attached two pics. They are small portions of a wiring schematic which show where the signals ground. They will be on the left and right side of the trunk. I need you to check them to make sure they are tight and not corroded or damaged. They are the black wires in the pictures.
Also, let me know if this happens if you turn the hazard flashers on.
Let me know what you find.
