Yes it can and will. At idle the engine and oil pump are turning slower,
less oil is being pumped,less oil pressure. When you come to a stop the
oil will slosh forward in the oil pan and if the oil level is low
enough, the pickup tube could be momentarily uncovered causing the pump
to suck air instead of oil.
