Find out if you have a code that is not throwing the CEL. I had this and it was a small adjustment in my tune but your description is almost exactly what was happening to me. It was definitely limp mode. A restart of the car, or several restarts, usually fixed it.

My problem tracked backed to a MAP issue in the tune. Did you wash or detail the engine recently? The paste below was the troubleshooting path I followed:

It is probably worth a shot to the check the MAP sensors:
1) Harness or connectors
2) Mass air flow sensor
3) MAP sensor
4) Evap pressure sensor
5) Intake air leaks
6) Intake air temperature sensor

Good luck. Limp mode sucks.
MAF also crossed my mind as i havent cleaned it as of late...
