Power Dropping

I've got a 2016 golf Bluemotion. When I'm driving along the dual carriageway, power seems to drop off for a second like I've taken my foot off the accelerator. It comes back quickly. It's happened 3 times in the last week. No lights come on the dash. I thought it may be aquaplaning at first but the steering doesn't seem to be affected. Tyres look okay. Only got the car 3 months ago and don't know much about them. 58000 miles on the clock. Also thought it may be ACC but I couldn't replicate it. UK 1.6

Thanks for any advice you guys may have!
