Car randomly lost all boost, then fixed itself?

This morning I was driving home, a 20 minute drive. I would venture to say the car was a little cold. I gave it some decent power probably 5 minutes in. As I started getting close to home, I realized my throttle was being very weird. The car was barely making any power at all. I looked at the JB4 app and yep.. less than 1 PSI of boost at full throttle.
I pulled over, turned the engine off, turned it back on, and it was back to normal.
Umm.. okay? Is this cause for concern? I'm pretty modded.

Sounds like you hit over boost, only a concern if it happens repeatedly.
You can pull the logs and see if the tuner folks can figure out what caused it.

I've heard this happens when boosting hard when cold. I had it happen to me when FULLY warmed up and I just pulled out hard on some stones and I guess the traction control completely jacked up the ECU and it went into the same limp mode.
Zero boost at WOT
The car felt like an NA 1.8 liter
shut it off, restart, back to normal hasn't happened since
