Unresponsive throttle at 60mph
2017 Durango STX (V6) with 27k miles. 2 hours into a trip back home, on the highway at ~60mph, the car suddenly felt unresponsive. Throttle stopped responding and the car started slowly decelerating (maybe due to mild incline). Power steering and brakes remained fully functional. Throttle action didn't increase RPM. I quickly checked all the gauges. No CEL, normal engine, oil and transmission temperatures.
Went to rest on the shoulder. By the time I safely stopped the car, the engine quit. Yet I think power steering and assisted brakes remained fully functional until I was parked. After couple minutes I tried to restart the engine. Starter kicked in for 10 to 15sec. Engine didn't start.
After 40min waiting for roadside assistance. I tried starting the engine again, it immediately fired and ran perfectly. Completed the ride back home (15min) normally.
Not sure what to think and what to tell the Dodge mechanic. This happened car loaded with the family and pulling a small camper trailer. Makes me very uneasy.
And of course warranty expired 20 days ago :-(
EDIT: Checked OBDII - no error code reported.
Any clue and recommendations?
Thanks.

I'd see if there are any codes in the computer. I'm assuming Chrysler hasn't done away with the key dance. Turn your ignition key to the on position but do not bump the starter. You will turn it on, off, on, off, on. The third time you turn it on, leave it on. If you do this without hitting the starter, the odometer will start to show any codes stored, even if the CEL isn't on. Now, FCA may have done away with this (I hope not, it's really handy) and if so, you'll need to get a OBD II code reader.

Thank you, I'll try that. Will also connect the OBD II and see what comes out.

I'm sure someone will correct me if I'm wrong, but I believe you have a throttle that is "drive by wire". In other words, no mechanical connection. I had a BMW like that and it would take spells of doing that. That's why I got it cheap. The throttle sensor on the throttle pedal was going bad. I replaced it and the problem went away. Ditto with my F-250 PowerStroke. In both cases, pushing on the pedal made no difference. Replacing the sensor cured the problem in both instances. I'd check my sensor to see if a foot kicked it or it's dirty. You may just need to clean it. The BMW was a sensor on the assembly and the Furd I had to replace the pedal assembly.
