[Solved] Loss of power on acceleration

I've got an issue that I can't seem to narrow down. i get a loss of power during moderate acceleration only on cold startup. It only occurs if the car has been sitting for hours, and it only occurs within the first 30 seconds of a cold start. After 30 seconds or so the issue stops.

It is most noticeable in 2nd gear. There are no codes. It feels similar to if DSC kicks in, but much less aggressive. Before I begin throwing money at an LPFP, HPFP and 6 injectors, does anyone know what this could be?

Solved: Replaced brake booster vacuum hose and grommet. Problem went away.
