Why does my car beep when stopped & the pile pressure light comes on.

What is your question?

Every time I come to a complete stop even if not in park by truck beeps & the oil pressure light comes on but as soon as I press the gas to drive it will stop. This has been happening for a few months. I’ve changed the oil gasket & it stopped for awhile and then started again

What makes this problem better or worse?

Driving

How long has your 2005 GMC Yukon had this problem?
