Is this normal ? I was at a track day @ Mid Ohio and coming down the back straight breaking very hard from full chat and as soon as I let off and roll on to go around the right hander at the end I have no drive , a few whacks of the throttle and it come back on line. Not the best way to take a corner. Whats the solution other than breaking earlier

I would also check your fuel filter and replace it with an inline one like Kowekiller did:
