Default Difficult startup after a reflash??

I have been tuning my friends turbo Camaro (Sluggish on here) lately and it's been giving us some trouble. The car will run/start just fine. We will do some data logging, I will make MINOR changes to VE, spark, etc, and try to start the car back up.

The car will crank up for about 2 seconds, then die, over and over. Eventually, it will finally regain it's senses, fire up, and run like nothing happened, but this usually takes 10-15 tries. When it's doing this, I can re-write the previous tune that was in the car, and it doesn't help at all.

I'm using HPTuners 3-bar SD custom OS, and it's a 2002 car/PCM.

Does anyone know what might be causing this?

IAT heat soak is a common issue.
