the o-ring that seals the oil pickup tube to the oil pump is notorious for causing your issue. it fails or shrinks letting air in which will not let the pump prime.

Always monitor the engine oil, keep it clean, and only use full syn! In the meantime drop the pan, clean the screen, and as Bronx stated, replace the pickup tube seal. Recheck oil pressure.
