Had the chance to ride the bike to/fro work today, after riding for a period of time and after revving the engine above 4K RPM, observed lost of power and intermittent power surges again.
....... plugged stuff back In wrong maybe?
Would not be the first time.

Happened to me first time I went in there. Not plugged wrong, but one hose not fully engaged and disconnecting, causing symptoms similar to @JingleJ
