Sometimes, car would stall after starting 5 or 6 times and then enter complete shut down mode. Wait, come back later, and it works just fine.
From reading comments on here regarding similar problems (and conversation with dealer) I agreed to buy a new gray key from dealer. They programmed it, but problem was still intermittent with new key as well. They next wanted to replace SKIM (and then they wanted to move onto BCM) but I wanted to do some more checking since they weren't exactly impressive on another issue.
I replaced ignition switch. Still intermittent problems. I removed Instrument Cluster Board and (a friend) resoldered the power connections, and visually checked it. I visually checked wiring connectors to BCM and PCM but they looked nice and clean.
"Mopar2" (?) posted similar problem resolved with new keys and new SKIM. At this point a bad antenna connection on current SKIM is certainly possible and for $100 to $200 I figure it is worth a try to recover a vehicle that my wife will absolutely NOT drive in its current unreliable state.
I have not tackled ASD relay, CAM position sensor, or the like as the VTSS light and the only stalling at startup symptoms really seem to point to an immobilizer system problem. At this point I sure HOPE it is the SKIM as I do NOT fancy the next step (BCM) that the dealer wants to take.
I appreciate your earlier reply. Any further input based on all this detail?

The info. I have, indicates with the light and all, you are on the right track. Dealer will have to program it for you. With only the SKIM being replaced, if they do it right, the new SKIM gets the key info. downloaded from the PCM. Still cheaper than a new car.
