Throttle Control Warning Light On problems of the 2009 Ford Escape

Had just come over the TN river bridge on i40 east in TN and was approaching mile marker 137 when the vehicle became non responsive to throttle with no dash indication lights. At first I thought fuel pump shut down because acceleration did not work. I knew the engine was still running by rpm and power steering worked. The vehicle was coasting in the left lane and there was traffic behind, in front and in right lane. I turned on hazard lights in hopes of warning the traffic around me. The semi behind me had to slow also and I could not change lanes at moment. Contemplating going left into the median and maybe striking an upcoming bridge rail or wait for open right lane and get to right side of interstate. I had an opening and turned off hazard flasher and then gave a right blinker, cutting off the semi behind who was trying to go around me. At that moment I thought we would get hit. Pulled over and the wrench light came on and no check engine light. Vehicle idled bad like a misfire and rpm gauge went up and down unsteadily. I videoed the fluctuation while pulled over. Turned car off and restarted no problem. Problem came back again 74 miles later in nashville at 88756 miles. At that point on i440e and i65 split the vehicle, without warning, shutdown again, became non responsive to throttle. Then the wrench light and check engine light came on and I pulled over videoed the fluctuating gauges. Turned vehicle off and restarted and lights went off and proceeded to crown Ford on thompson lane and the service dept was closed. This issue also happened 5 times on 9-3-2012, between mileage 89,9002 to 89,1181, while in alabama/TN. Example going uphill, and also coasting into someones driveway at night . This vehicle still currently has the trans flare issue even after two pcm reflash. But Ford cant get it to act up. I thought maybe this issue was related.
