Vr stalling

[vpcalais5.0]

Hey guys can u please help me out with a problem my Vr starts perfectly fine runs perfectly then after 30 seconds it drops idle and stalls I've replaced the fuel filter and pump but it's got the same problem I can also here a weird noise which is coming from the back injector or fuel pressure regulator witch sounds like water escaping into air so was thinking can a faulty injector cause this

First up Id do an error code check to see if any error codes are showing up.
