Narrative:

During previous flight noted that the left and right engines had a large itt split. [The] flight was too short to check see if it was just a transient issue. On this flight we had more time to look at the issue. After climbing out of 10;000 ft the power was increased to climb power and the itt split returned. Itt was over 840 [degrees] C on the left engine. I took a quick set of readings to pass along to maintenance and then sent an ACARS message to let them know about the issue we were seeing. Maintenance control sent a message back and asked us to see if it was still and issue with the engine speed switches off. We reduced power and then selected them off. I advanced the power to climb power and noted that it was similar and maybe a bit worse. I pulled the power back to about 1/2 throttle travel on a slow count and the captain reselected the engine speed switches back to the on position one at a time. When the left engine speed switch was selected there was a short small shutter and the engine flamed out. After the required moment of disbelief we informed ATC that we had lost an engine and needed to descend. We proceeded to run the single engine QRH and restarted the engine successfully. During the process of running the QRH we had an exchange of messages with maintenance on the issue and they stated that they should have had us run a QRH for engine speed control. Reviewing the procedure; we didn't have any of the issues that you'd run the QRH; but our procedures were essentially the same as described. After the restart we reviewed the situation and concurred that we saw no evidence that we needed to divert. We returned to an intermediate altitude and continued to destination. We also coordinated status with dispatch via radio.

Title: CRJ200 flight crew notes a large ITT split between the left and right engine during climb and notifies Maintenance. Maintenance requests that the speed switches be turned off and the ITT checked again. When the speed switches are turned back on the left engine flames out. The left engine is successfully restarted and flight continues to destination.
