Vsa Warning Light On Problems of Mazda CX-5

Running errands on way home on the highway while on a hill suddenly incurred loss of power, check engine and driving stability warning lights came on. Pressed gas and no change in speed. Speed dropped from 45 to 20 and had to move to shoulder. Other than loss of power everything else functioning normally. Managed to return home via back roads and avoidance of hills. Speed improved somewhat once completed climbing hill but as neared home car's speed topped out at 20 mph, total trip 4 miles or so. Once in driveway turned off car and then started again neither the check engine light nor the driving stability came on again. Car well maintained first time this has happened in 2 years of ownership. Will be taking it in for service and see if problem can be diagnosed.

While driving vehicle on frwy, started losing power fast. As if the engine turned off. At light, traction light, stability control light and check engine light came on. Pulled to side of frwy turned car off, sat there in disbelief. I then turned the vehicle back on - only check engine light stayed on. Had power as if nothing had happen diag found code p1738, p0847. Galpin Mazda called tech line and they were told to perform a reflash to the pcm. This happen again about 2 months later. But this time all warning lights turned off after restarting. I will mention it on my next service visit.
