power switching

Is it possible to cycle the 3.3v power pin on the arduino without having to cycle power on the whole unit?

No.

Do you need to reset something behind that supply?
I have that problem with my GPS unit. One solution could be to control it by 1/7th of the uln2003 transistor array, it takes one output anyway.

Better ideas will be taken with gratitude.
