Fuel Pump problems of the 2010 Toyota Corolla

2010 Toyota Corolla first experienced problems June 2010 (car purchased March 2010) on a warm day I. E. 90 degrees the engine shut down, coasts to a stop. Still able to steer to get off the road. Wait 10 to 15 minutes and car will restart. The first time this occurred my son was driving the vehicle, totally shocked him. The next time I was driving on an interstate through a congested mountain pass, was fortunate that no semi trucks were directly behind me and that there was a shoulder on this stretch. Took into dealer after same experience on 2 trips. They were unable to determine a problem. June 2011 drove 200 miles on the road, then drove in town same day with multiple stops. Driving at approx. 35 mph, car jerked, stepped on gas with no response. Able to coast to a stop at a red light. With traffic backing up behind us and car would not restart, driver behind us and my octogenarian father pushed the car around the corner to a church parking lot. Called triple aaa for a tow, after waiting a half hour tried to start car. It started. Called triple aaa to cancel tow. During the next 1 to 2 miles the engine shut down 3 more times and each time was able to coast out of the roadway. Finally had vehicle towed to local Toyota dealer. They examined vehicle next morning and I was told that there is a problem with the fuel pump on 2010 and 2011 Toyota Corollas in heat and at altitude. Engineers are working on a new fuel pump. Toyota does not know when a new pump will be available. I no longer feel safe driving the vehicle as you do not know when the engine will shut down. Was told by the dealer the vehicle is safe to drive. Just put on flashers and coast to side of the road. Of course there may not be a place to pull over and what happens if you are in heavy traffic on the freeway with many vehicles going 70 mph. Toyota knows there is a problem and they are telling customers to continue driving the vehicle. This doesn't make sense.
