The most likely suspect is the oil pressure sending unit. Check the pressure with a mechanical gauge. intermittently low pressure can be caused by debris holding the pressure relief valve open but more commonly if it's not the sending unit it's due to a spun bearing that occasionally orients itself to block the oil passage in the journal.
