Other Fuel System Pump problems of the 2003 Nissan 350Z

My car for the last year will drive 5-7 miles and stall in regular traffic. We replaced the fuel pump. I finally have enough $ to take to Nissan. They came back with it needs all 2 cam shaft sensors and crank shaft sensor replaced. When I go on line and search my 2003 350z touring edition recall, there was a recall for this problem as it appears the wires can break inside due to temp on solder joints. I would like to know if this is this a problem that was noted on a recall and this is an ongoing problem with this same model, why now am I going to pay Nissan $1200 for the repair that should be covered. I need this investigated.
