This same hot-start problem was discussed at length in several posts
just 3 months ago. My theory is that after longer times (overnight)
the engine cools enough for the ECU to decide to use a "cold start"
program, which employs a longer duty cycle for the injectors. Faster
fuel delivery-->faster start.
