When you said that you use 93 or highter, do u mean octane level? Cuz you don't need to use as high. The fuel system isn't design to use that. Nic.

If not, look at the bottom of the pump and see if there is a circular screen covering the inlet. If there is a space for one, and the screen is not in it, you know where is probably fell off at.... Check it for fuel leaks, fuel pressure, maf performace, baffles in the tank, etc. It's probably pretty obvious what's wrong....
