This started yesterday and since has kept happening. Out of no where my check gauges light/ beep went off and I noticed sometimes when I brake my oil meter needle will drop all the way down, then will go back up to the half way point. Any idea what can cause this?

Bad oil sender switch. When it dips to zero the check gauge light comes on.
I've been fighting this battle for years. Been through half dozen senders.
Supposedly an official OEM Mopar switch might stop the problem. I have yet to get one.

Or...maybe you really are losing oil pressure.

Well I took the common sense route and decided to check oil level, yea it was low as f*ck! So one I guess that oil sender switch is still bad since it never said the oil was low? Also now need to figure how I lost that much oil when I have no marks on my driveway to show it's a leak...

The sender will not move till about 3 qts low. But, when it hits 2 qts low, any hard stops or turns will cause it to drop.

What engine?

Just check oil every week or so. I check it every other fill up.
