I was going to use my laptop, but I may just use build a dedicated pc and use a spare tv I have for a monitor.

Mine is not a TV but just a cheaper monitor...I have an HDMI cable from my laptop to the monitor...I mounted the monitor on the lid.

I recently purchased an 05 C6 ls2 base. I experienced a random shutoff while my car idled for about 2 mins. electronics stayed on , i then drove it home for about 7 mins, experienced two shutoffs , both gave me the "shift to park" message my dash stayed on however my engine cut off. I then scanned my car for codes & got a lean on banks 1 & 2. Mind you no CEL. I then took it my local shop & they recommended changing my MAF sensor. This could possibly be responsible for my shutoffs. We had then changed the MAF. Codes cleared. Nothing came back. After a week or so after driving i experienced another shutoff. dash still lit. mind you i have no experienced any other weird things with the car and the car still scans for ZERO codes. Looking for recommendations or suggestions.
My C6 does that now and then, I get the "shift into park" reading, I just push the shifter forward and the lights go out. I need to adjust my shift cable to fix it , soon as I get off my lazy butt to do it.

The lean code shows that it had a lack of fuel. The problem is either the fuel pump relay is going bad. Or the fuel pump relay pins in the fuse box are not getting good connection. Super common on the C6. I had this
same issue. My fix was to tire in to wire up a whole new relay and positive wire to the fuel pump. There is a harness infront of the driver rear wheel in behind the liner hat goes to the pump. I tied into the system there.
