problem with camera settings on my a6000 + epz 18-105 f4 G OSS .. 

Aperture priority set to f8, 350s  first frame ok 5 minutes later.....  2nd and 3rd frames the Aperture changes to f4 with an increase of shutter speed the only adjustment  I made was to zoom length 25mm -28mm-31mm

Was this a one off, or a regular problem?

If you are in Aperture mode it could be something as simple as knocking the control wheel without realising it.

I had a similar problem with knocking a control wheel, which kept changing my exposure compensation.

Yes I think your right I've been taking a closer look at the camera settings menu and Operation controls and the wheel on the back does change the aperture setting and what a pain its so light and easy to move accidentally with the other settings you have to select first then move the wheel .. doesn't seem to be a way of turning it off either.. cheers thanks for help.

further to my question.. the wheel on the back of the a6000 can be turned off in settings by selecting ..Dial/Wheel Lock.... this disables it temporarily , then hold down the Fn button for a moment to lock/unlock .

Maybe if you sleep with your owner's manual you can figure it out.  You can set the dial to do whatever you want.
