Having fuel issues once I hit 3000 rpm truck shuts off

I have a 2016 glc 300 , and over the past 2 days I been having fuel issues idk if it’s the high pressure fuel pump or the low or even the sensor , car will let me drive it for abt 30mins -1hr if I don’t go fast or hit the throttle to hard very gentle push my feet on it but it will cut off while driving if I hit the throttle to hard and I can’t drive unless it’s slow just wondering has anyone else came across this and also code p0087 popped up on my reader
