The only way to tell for sure is to hook up a good mechanical gauge to the oil pressure port and see what the reading is. The oil pump might be getting weak or bearings are getting worn. Oil is thicker when cold which shows up as higher reading which then drops as the engine warms. LS1's were known for bad pumps.
