Last night, after work, it took three tries to get my 850 started. The first two, it would quit a second (if that) after starting. This morning, It was twice although it did sound/feel a bit different than last night, it happened so fast I can't really tell you how it was different. This isn't a slow cranking issue.

After getting it started it behaves normally. A warm restart is also normal.

I've been researching crank and cam sensors, along with the fuel pump relay, and all those seem to present with the engine cutting out at any time, or not starting at all. Mine is just quitting on a cold start.

Any ideas?

If the coolant temperature sensor (ECT) is aged, the cold start fuel injection wont be correct. There is no 'extra injector' like on First generation fuel injected cars.

If you know how to use an Ohmeter, you can check the performance of the ECT to spec.
