The problem is most likely a bad connection at the battery or the underhood fuse panel behind the battery. Recheck these connections and included the ECT (Engine Coolant Temperature) sensor (wires and harnesses).
Fuel system? Relative to how gasoline engines work, one that has sat during the
8-hour workday is nearly as 'cold' as one which has sat overnight
(overnight will dip mebbe 30*F more, but this is practically irrelevant
to an engine). The one major variable is volatility of the gasoline, which is affected
by atmospheric temp especially when the engine isn't warmed-up. Starting this month (and continuing until fall) the 'blend' of gasoline
will change from 'winter' to slower-vaporizing 'summer' in most regions
of the country; you may have it now, or from some specific gas station.
If the car's Inlet Air Temperature (IAT) sensor (in the airbox), is
faulty and reading too high, then the combination could push your engine
'over the edge' in terms of the PCM trying to set the proper richness
for 'cold start.'
Keep us updated.

The process for the passlock relearn is correct. If by chance the relearn does not work, you may have a fail component in the system. Go to this link for options to fix this yourself.
