Check Engine Light On problems of the 2007 Jeep Patriot

On 09/17/13 at 0858 hours, I was driving my 2007 Jeep Patriot on the I-17 frontage road when the vehicle began to lose power steering. Prior to the loss of power, I was travelling northbound on an even concrete surface at approximately 50 mph in normal traffic conditions. When the vehicle began to "act up," the light for my electronic stability control turned on and the esc became active and my check engine light began to blink amber. Due to esc, my vehicle was extremely difficult to control (once again this was on an even, paved surface with no conditions requiring the esc to activate). Along with the esc becoming active, my vehicle began to stall and lose power. My engine would peak at a mere 2000k rpm and at about twenty miles per hour. Thankfully I was only on a frontage road and was able to quickly pull into an industrial area, however, if I was on I-17 (which does not have a shoulder) I would have been in great danger. Once stopped, I had to stop/start my engine four times for the esc and check engine light to deactivate. Once they did the vehicle operated normally. I took the vehicle to Jeep dealership in north phoenix to see what was wrong with the vehicle. They advised it returned a "torque request signal denied" historical code for when the incident occurred, which "doesn't make any sense. " I believe the above incident is related to two events that happen on 9/14/13. During two separate right turns the vehicle began to stall through a turn only to jolt and regain power.
