Oil pressure dropping

mardi 20 septembre 2016

So recently my car has been having a new issue, while driving along my oil pressure drops and my car turns off while im driving it. I have aftermarket gauges so i can see it going to 0 bar and then the car goes off. Also the car starts shaking between 4k-6k rpm. The idle has become very rough aswell. What could the issue possibly be?

Thanks,
