A clone Tech 2 scanner will be here Friday. I can use this for my 2009 Cadillac CTS as well, so it is easier to justify the cost.

A CKP re-learn will be performed. If this does not help with the cutting out problem, and my guess is it probably won't, live monitoring should be useful to help narrow down the source of this intermittent problem. It will usually fail briefly once or twice in a ten minute drive, so having a Tech 2 set up to monitor some key signals should help.
