    How low is the oil pressure dropping?? Its normal for it to drop somewhat when the engine heats up, since the oil thins out with the increased tempuratures and flows much easier through the motor.

    What temperature is the engine getting up to?? Sounds like you may have a cooling fan issue, perhaps a bad cooling fan relay or coolant temp sensor.

    How is the oil level? Do you notice any leaks anywhere? Hopefully you don't have a head gasket issue!

    Motor oil thins out as it heats up. Find out the cause of your cooling issue. Then your oil pressure issue will be corrected as well.

    Start with your fan operation and get a coolant flush done. Also under what condition exactly does it do this, all the time or on the move?

    Pull off the upper rad cover/airbox and see what kind of crap has gotten sucked in there. If that air space get blocked, or the lower deflector under the car gets broken off it will cause the car to over heat.

    When was the last time you checked the coolant level? They don't like getting too low.
