Lose Power Steering problems of the 2010 Ford F-150

There have been 3 times now that my vehicle has randomly died while driving on the highway and city streets. With the engine not running I lost power steering and almost couldn't make a turn. No warning lights, no chimes. Looking into it myself I found that the fuel relay 20amp fuse was melted and the plastic around the terminal also melted. Ford has a TSB out for this issue but I feel it should be recalled for safety purposes as there is no warning and you lose all power. Little to no steering or brakes until you come to a stop and pop the hood open and wiggle that fuse in hopes that it will make contact again. This means that you could be left stranded or get into an accident trying to stop. Many people in online forums have had this same issue and it needs to be addressed accordingly.

Leaving red light, truck stalled. Oil light came on, lost power steering, brake. Was able to coast at an angle to the side. Could have caused an accident or traffic jam. Put truck in park, waited a minute, turned back on and gave it gas. Ran fine after that. Took to dealership next day. They said would not be any way to know what happened without pulling engine apart. Suggested multi point inspection and tune up. Did not mention this issue occurring previously or the numerous complaints of this issue online. They found a dusty air intake sensor that could have caused the problem. Changed spark plugs and performed tune up & oil change. Incident happened again leaving gas station pump on Dec 29, 2014. When restarted, it cranked several times but wouldn't fire up. Tried 3 times before successful start. Ran fine after that. Afraid a stall at high speed or when pulling my horse and trailer will cause major accident. Have seen complaints of fuel purge valve or throttle body butterfly valve causing this. Needs to be addressed by Ford.
