Engine quit right after 1st start

Many 912is engines do not like to run below 2500 rpm when cold and will stop.  ????
Keeping the RPMs high for about 10 seconds will let the symptom pass.
Make sure you have the brakes set before cranking or it gets exciting fast!!!

It is not uncommon for the ECU to reset on Startup.
My engine typically turns through one compression and then stops for an instant trying to get past the second compression.
After that, it cranks vigorously and starts after two revolutions.
When it stalls on the second compression the battery sags as it gives its all to the starter.
The voltage drops low enough that the ECU and the Panel Brown out momentarily, causing the reset.

My experience with this issue saying replace your battery in order to have higher voltage. 

I had this problem and changing the battery solve all problems. 

I agree with Micha that failure to rotate the engine more than 1 compression is a sign that your battery is in VERY poor health, and probably needs to be replaced.

This isn't that uncommon for the iS engine. I have heard many say theirs starts up then quits. Since the rpm is usually set a little low from the factory I tend to crack the throttle even though the manual says throttle all the way back. Then the start up is right at 2000 rpm and not too low to beat anything up and enough fuel to keep things going.

Try it and see if it works for you.

I guess this may be more a personal preference, but it does work. I usually increase the idle rpm some at the annual which seems to help and make it run a little smoother when people pull the throttle back.

Well, my procedure for turn off the engine is the following:

When arrives at the parking, I adjust the throttle to 2300-2400 and turn off the A&B lanes.

Next starting is with the same throttle position. 

Together with the healthy battery no problems at all.
