Changed oil and filter went down road no problems got off highway made several quick turns and went thru two roundabouts back on highway. Oil pressure fell to 15 pounds. I pulled off road let it idle it then went to 5 pounds with chatter turned it off waited 10 seconds started back up pressure went to 40 pounds. Drove back no problems, in yard drove a serpentine pattern and pressure eventually started to fall to 10 to 15 pounds. Stopped, at idle had 5 pounds with chatter. Shut off engine waited few seconds started back up to 40 pounds of pressure? Could something be in oil pan getting picked up and blocking draw tube?
