Default misfire/sputtering entering boost

ive been driving around at 15psi with no problem and all of the sudden the car WILL NOT boost every time it rolls into boost it just starts puttering and misfiring and reads 0psi. Ive changed everything but the plugs since the new motor would this have anything to do with it?
