Re: acting wierd after startup
Pinhole in the fuel line inside the fuel tank, from rubbing on the inside of the tank. Definitively diagnosed by fuel pressure to the injectors.

Leading up to the stuttering, you can expect the machine to be a bit on the hard-starting side. It should fire right up. If you have to spin it for a while before it catches, the pinhole is probably what you have. Also, listen for a bit of a hissing sound, coming from the tank.

Enjoy,
Rich P

I would be. It's giving you a "Heads Up" or warning before it actually fails and leaves you stranded in the middle of nowhere or worse yet an engine stall out when pulling into traffic.
