Fabia VRS MK2 loss of power under acceleration

Hi All,

Help needed, I was pulling out of a junction earlier today and the car lost power under acceleration twice with no engine fault lights displayed, after this the car was going a little slow e.g not changing down in gears but after awhile the car went back to normal. After letting the car cool down I then did a second journey to see if it would happen again and it had a little hiccup when asking more power. Any ideas what this could be?.

Thanks

Dan
