2013 Dodge Caravan

RIDING ON A HIGHWAY GOING ABOUT 55-65MPH, THE ETC (ELECTRONIC THROTTLE CONTROL) WARNING LIGHT CAME ON, FLASHED AND BEEPED. THE LIGHT WAS A RED LIGHTENING BOLT WITH LINES ON EITHER SIDE. THERE WAS NO TRAFFIC AROUND ME, I WAS CRUISING AND OUT OF NO WHERE FOR NO APPARENT REASON, THESE LIGHTS CAME ON. I REALIZED THE ACCELERATOR WAS NOT DOING ANYTHING, I HAD LOST POWER. I COASTED INTO THE NEXT DRIVE WHICH WAS A CHURCH. I PUT THE CAR IN PARK, SHUT IT OFF AND RESTARTED IT. I HAVE GONE ABOUT 100 MILES SINCE THAT HAPPENED AND HAVEN'T HAD ANY PROBLEMS SINCE. THE TCS (TRACTION CONTROL SENSOR) LIGHT ALSO CAME ON AT THE SAME TIME AS THE ETC LIGHT, WHICH IS A YELLOW LIGHT WITH A CAR AND ZIGZAG LINES UNDER THE CAR. UPON RESTART BOTH LIGHTS WENT OUT. I AM CONCERNED THIS WILL HAPPEN AGAIN UNDER MORE DANGEROUS CIRCUMSTANCES.
