Had this same problem with my 08 Suburban LTZ. Cold start it would run at about 10psi and would immediately begin to drift down to 0psi. Long story short, we dropped the front axle and oil pan( which takes half the time of pulling the oil pump) and replaced the worn oring in about 5 hours. Now cold start idle produces 60psi and the same pressure at highway speeds once warm.
