2013 Mazda CX-5 stability control problems

I was driving at the listed speed on the new jersey turnpike. Without warning, the vehicle went from sixth gear to fourth, rapidly losing speed in the far left lane. The tire pressure indicator light came on flashing, and the traction control light came on solid yellow. I pulled the vehicle onto the shoulder to check the tires, per the indicator, and noticed none of the tires was deflated.

When driving approximately 65MPH or sometimes less the tire pressure, traction control, emergency light comes on. The car seems to lose power and shut down. It happens countless time twice with my two-year-old daughter on the highway. When I take it to the mechanic they run diagnostics test and can't pick up any codes. Because its not duplicating any issue they return the car to me after they reset all the computer. But the issue is still not resolved.
