After engine was warm I was sitting at idle for approx. 5 mins. The vehicle started running rough and then I noticed the oil pressure gauge drop to 1/4. When moving it goes back up to 1/2 on gauge. Not sure if it is normal and I just didn't notice the gauge before

There should be a, "Normal" range on the oil pressure gauge. If it is within thisarea it is okay. The oil pressure will drop after the engine reaches temperature and in the winter the oil pressure will be higher because the oil is thicker from the cold. If it si running rough or the idle is a bit low, it will be lower thatn usual. It should go uoo when you rev up the motor. The biggest thing is to note where it usually is and then if it drops lower or oout pf the, "Normal" zone, pull over and stop the engine immediately.
