Car Will Not Accelerate problems of the 2006 Ford Expedition

First occurrence exhibited flickering dashboard lights before the electrical system went completely dead and the engine quit while accelerating at approximately 20 mph. Put vehicle in neutral and was able to restart engine normally before coming to a stop. Have experienced several short instances of dash flickering over the past couple of weeks with no apparent engine problems. During that same period there have been approximately 4 instances of the electrical system being completely dead upon the initial attempt to start the engine. When this happens, the only light that is illuminated on the dash (or anywhere else for that matter) is what I think is the airbag light; however, normal electrical power has, thus far, re-appeared within 5 minutes and the engine then starts and runs normally. Yesterday the "check engine" light came on and I was able to pull a code of p0119 (engine coolant temperature circuit intermittent) upon returning home. I subsequently cleared the code, but the reader indicates another code is "pending". I believe this is a symptom of a larger problem. I have not experienced a "engine failsafe mode" warning message, but this complaint is very similar to many others already posted and I agree with the related safety concerns and need for a recall.
