Question about 2002 Chevrolet Chevrolet Tahoe
It dies while driving when you try to accelerate fast. It starts to pick up speed but then dies. It will start right back up if you turn ignition off then turn it back on to start. If you ease the gas pedal down it won't die.
Can be caused by many things but i would start by checking fuel filter and fuel pressure

Ok this was all after the car was all warmed up how far can you go from a cold start until it "dies:?
I want to suspect a crank sensor or ignition module just because of the symptoms if nothing happens until the egine gets hot ,typical of a failing crank sensor andignition module, always replace them togother.
But there is one more culprit, the catalytic Converter, see they break up inside and over time the catalyist bounces around and becomes a ball, on acceleration the presssure of the exhaust pushes the "ball' of caytlist into the exhaust pipe opening restricting it until it shuts off the car. You pull over the pressure goes away the "ball" falls back into the cat, you start again and it starts all over again. I would hve the cat tested and you can do a test yourself hit the cat on the bottom with a hammer and if you hear some rattling inside when you hit it yhe catalist is broken and is likely your problem.

SOURCE: 2002 chevy malibu won't start
Does the starter make any noise or click when you turn the key to start? If it does not, chk. battery could be bad, and battery cables could be loose or corroded. If there good and clean and battery is good try tapping starter see if it will turn and start if it does or still clicks starter bad. It could be ignition switch if it does nothing at all, but if it clicks most likely its starter.

Fuel filter. Timing/timing chain. Idle air control valve. Idle sensor. Vacuum leak. Probably one of the above, but the filter is cheapest place to start. Change your air filter too, if you haven't for a while.

Testimonial: "Great thanks so much! This will be a place to start, more than chevy dealerships have given me! Appreciate your time :) Thanks again!"
By what your stating, that it starts and dies every time, It seems to be fuel related. You need to perform a fuel pressure check. You will need a pressure tester, one that would at least be able to read pressure to a maximum of 150 lbs of pressure. Although you really only need about 50-60 pounds of pressure to maintain proper fuel injector operation. There is a test port located on the fuel rail where you would conect the pressure tester. The test port is usually located on the drivers side of the engine near the rear section coming up from the firewall. Unscrew the pressure port cap if its still there and connect your tester. But also keep in mind you may have fuel pressure of some sort in the rail so be careful. While the tester is screwed to the test port you want to cycle the ignition key on and read pressure, you may want to repeat this several times. You must have at least 50 pounds of pressure, if so it should start. If you are losing pressure while your maintaining a visual check on the tester it could also be a faulty pressure regulator/fuel pump or even a rubber hose connection inside the fuel tank that connects the fuel pump to the fuel line.
