Occasional loss of all boost?

I've noticed maybe 5 times in the year I've owned my car it will seemingly lose all turbo boost while I'm driving it. Usually happens on hotter days at highway speeds, but it's happened on cooler days as well. My boost gauge on the torque app shows 3psi at full throttle, making it very hard for the car to maintain freeway speeds let alone pass or merge. Stopping the car and turning it off then back on resolves the issue.

What at causes this? Should I be concerned? The car is a 2014 1.4 with a trifecta tune and intake resonator delete.

Mine does this in 4th gear if I lock it into forth via manual mode and put it to the floor to get on the freeway. I goes good for a few seconds and then I get 50% throttle, as displayed by torque pro, low boost but no codes. I am thinking it is the start of the end for the turbo and may be a wastegate issue.
