2005 cadillac cts 3.6 engine - yesterday, car would start

Customer Question

2005 cadillac cts 3.6 engine - yesterday, car would start and shut down within 2 seconds. held throttle open (approx 2k rpms), still shut down. I was able to observe crank rpms until eng quit spinning. there are no codes in pcm. today, car starts and idles/runs fine in park, but shuts down as soon as the gear shift lever is moved. I also observed that the instrument cluster shuts off (like key is turned off) when the lever is moved out of park and cluster comes back on when lever is moved back into park. I have a Maxisys pro. the pcm (and other systems) appears to have voltage to them when this happens. I get the impression that maybe anti-theft is causing this? any ideas?
thanx, Kirk Riddle
