Fuel Pump problems of the 2010 Toyota Tundra

I have a 2010 Toyota Tundra that has about 10,000 miles on it. About two months ago I started noticing the truck will randomly have a sudden loss of power. It happens mainly when it has been sitting all day. It's kind of scary because when you are pulling out of a parking lot or making a left hand turn the truck will all of a sudden have no power and then it will jolt forward. I have not taken it to the dealer because no indicator lights are coming on and that's usually the only way they know how to fix problems. I have read a few forums that talk about this problem, one guy said he had his truck in and out of the dealer for 4 months and they basically ripped his whole truck apart. They finally came to the conclusion that the wire harness under the dash that goes to the fuel pump was loose and causing the problem. I called Toyota and the dealer and they told me they have not had enough complaints yet but when they do they will probably come out with a fix. I haven't done much since mainly because I don't want the dealer wasting my time and taking my truck apart.
