Could be losing spark... what spark plugs are you using?

But yeah need a lot more details... is it cutting out like missing, stalling?? What's your entire setup?

Perhaps your wastegate is leaking, causing a spike in boost.

a 50 trim @ 10psi with stock injectors will melt forged pistons just as quickly as cast.
get some bigger injectors, and get it tuned.
