Almost sounds like the classic cold start intake problem........ I had thought that this had been corrected in production but possibly not. Does the problem only occur when the motor is cold or can it happen also on a hot restart?

When its cold
I'd have it scanned for any pertinent CMDTCs to start with. Two common possibilities are the IAC and the lower intak manifold seals....
