Your symptoms pretty well match a fuel injection system loosing line pressure while sitting.

Typically, the fuel pump doesn't start pumping usually until the ignition starts pulsing from the engine cranking over. So the residual line pressure is what makes the fuel squirt out of the injectors correctly.

When the line pressure is low, the fuel injectors dribble instead of squirting. This gasoline doesn't burn, and the engine doesn't start.

With more cranking, the line pressure builds, the injectors start squirting instead of dribbling, and the engine finally catches.

It's usually a poor catch as it starts, the engine runs a little rough, and belches black smoke as the dribbled gasoline burns off in the cylinders and exhaust manifold.

So, I'd suggest a pressure check of the fuel rail.
