You need to replace the fuel pump, there is a sensor that is inside the pump called a sending unit, this sending unit measures the amount of fuel in the gas tank, and also since your car is stalling I would definitely say that I would start by replacing the fuel pump!

You need to check fuel pressure carefully. This happens when tank is so full of dirt that the pump screen gets clogged. After sitting down several minutes, some of the dirt settles and the car can be restarted, but happens again. Refrain from starting to change every sensor without knowing what is the real cause, because you could be thowing money and not fixing it. Aldo check pressure regulator is functioning correctly.

You have a bad fuel pump - probably the pump motor has gone bad or there is a loose wire. Either way, the pump will need to be removed to be repaired or replaced. Your car stalls because it is not getting enough gas. Keeping the tank full may help, but you are only putting off the inevitable.
For the age of this car it is a combination of both the fuel filter and pump, i owned one several years ago and found that the gas tanks are prone to rust inside, if you have replaced the pump and filter you may want to drop the tank again and check the screen on the pump if it is brown you have rust in the tank: another problem i had ( if you bought an oem pump ) they tend to slip out of position, you can tie the pump it place so it doesn't move......
The fuel pump is a good place to start since I doubt if the timing belt has broken in a vehicle this new unless you have been racing it. Yes, the pump is submerged in the tank. It could also be the fuel filter and that should be located under the passenger side of the vehicle near the gas tank itself.
Check the Fuel Filter and pump. It sounds like you have an over heat problem in the fuel pump unit or air in the fuel line that is causing vapor lock. This can happen when you let the gas level get below 1/4 tank depending on the temperatures in your area.
Try checking the exhaust flow when someone else is pushing down on the gas petal.The farther the petal gos down,the more exhaust should be coming out. I replaced my catalitic convertor at 44000 miles, it was clogged. I had them install a high flow type.
You could have gotten bad gas in your tank. Did you try dry gas at all? Also, bad gas can leave alot of sediment at the bottom of your tank, waiting for the right movement to get moving into your system. A new filter would only get quickly clogged again. I had this happen- got gas from a station after a flood- fuel tank had to be dropped and cleaned out.
Fuel pump,Fuel pump, Fuel pump,,, high mile cars will always out live their fuel pump. The stalls will become more frequent. But first change fuel filter if it has one outside the fuel tank, if it has it in the tank just replace the pump at the same time. Also next time when it stalls bang the bottom of the tank with your hand and try starting.
You need to check the fuel pressure to the TBI. I just fought one which was doing the same thing. I pulled the fuel tank to replace the fuel pump. It turned out to be the short hose from the fuel pump to the steel line coming out of the tank. It had a split in it so I wasn't getting enough fuel pressure. Some places show two pumps available. One you can pull the unit and replace just the pump. The other the pump and sender are all one unit. Hopefully you have the first one. The second is around $300.
The easiest way to get to the top of the tank is to pull the front 6 bolts mounting the bed and loosen the back two. Take the three screws from the filler neck and unhook the rear axle vent tube. You can then take an engine hoist and lift the front of the box. You can get right to the pump and gauge assemble in the top of the tank. Most times, this works easier than emptying the fuel tank and removing it.
