It's common for oil pressure to drop when the engine RPM drops to low. I doubt the oil pressure going up and down has anything to do with making your car want to stall. If I had to guess I would say the tune is off causing RPMs to fluctuate and that is causing your oil pressure issue or if you have a radical cam then you're trying to get it to idle to low and need to bump the idle up.
More details on your engine would be helpful.
