Sorry, I've never worked with OLED displays. However, as its current consumption is so high, you can't safely drive it from an Arduino pin. Use another P-channel mosfet, although this time you can switch it directly from the Arduino instead of using an additional transistor for level shifting.
PS - don't from the data you posted, looks like the oled display is a 3.3V device, So you'll be switching 3.3V to it, not 5V. The I2C pullup resistors should be connected to the Vcc pin of the display.
