ERJ 135 First Officer reported a rejected take off and return to the gate after a SPS2 Fail red EICAS message were displayed.

Narrative

After holding short of Runway XXR at taxiway 1 for some time we were cleared for take-off. Upon lining up on the center line and being transferred flight controls; I advanced the thrust levers to take-off thrust. Before I was able to say; 'Check Thrust' a master warning sounded and the Captain and I both noticed a 'Stall Protection System 2 FAIL' red Engine Indicating and Crew Alerting System message as well as an additional caution message; both of which quickly disappeared by themselves. At about 15 kts. we assumed the reject duties; the Captain took controls and I pressed the yoke forward and let ATC know we were rejecting and needed to taxi-off. We exited the runway and called Maintenance who requested we return to the gate. We taxied back where the fault was signed off. The subsequent take-off was successful with no abnormalities. The gusty winds we think unevenly moved the position of the Angle of Attack sensors which likely caused the issue. Perhaps more routine checks of the Angle of Attack sensors when windy conditions exist.
