RPM Hesitation???

I’m finding that in all of my cars on occation I’m getting a 1-2 second hesitation in the rpm, it’s like the engine stalls out & cannot increase its rpm thus slowing acceleration. It’s most obvious in high revving vehicles such as the Veyron, Aventador & vehicles of this type. Has anyone else noticed the problem & does any one know a fix? Thanks.
