Check the fuel pressure. It needs to be 55 or higher no less.

Have you checked the timing? It sounds like it may have jumped time.

SOURCE: After running for about 10-30

first thought is that the catalytic converter may be plugged. when plugged the engine will run until it builds up enough back pressure to kill the engine. after it sets a while the pressure is released and the car will start again. you should be able to start it up and observe how much force your exhaust pipe has. it should be strong at first then decrease to almost nothing before it dies. try that and check back.
remember that any of the new parts could also be bad so you may need to do a pressure check on your fuel pump

did you try to remove the code # with a diagnostic code retrieveing tool, this will remove the light from being on in the system, providing the computer is functioning properly, if you do not have the tool to do this with, then disconnect your positive battery cable, for about 1 minute, then reconnect it back up, and see if light is out. you will have to reset your vehicles clock, and possibly some radio functions.

2009 chevy tahoe fuel pump wont shut off

The fuel pump control module is controlled by the ECM - engine control module , Possibility of DTC'S stored ! You need to take to Chevy Dealer !
The engine control module (ECM) supplies voltage to the fuel pump control module (FPCM) when the ECM detects that the ignition is ON. The voltage from the ECM to the FPCM remains active for 2 seconds, unless the engine is in Crank or Run. While this voltage is being received, the FPCM closes the ground switch of the fuel pump and also supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.

1996 suburban with 5.7l have good fuel pressure, sparks at the plugs, cranks with starter fluid but wont crank when i disconnect the crank sensor.

when you say good fuel pressure is it 55 psi with the key on and engine off? any thing less then 50 psi will not start the engine. if the engine starts with starter fluid then the problem is in the fuel system.

If i let my 96 suburban sit for a couple of days it wont start but if i drive it everyday it starts up fine

If it cranks but won't start you might have a fuel pump issue that is intermitent or a plugged fuel filter. You can check this with a pressure gauge at the end of the fuel line.

2003 chevy suburban wont start in the morning after sitting over night, if it has less than half a tank of gas?

it sounds like you have a fuel line problem inside the tank,maybe a pinhole, once fuel level gets below pinhole the line loses pressure. once it loses pressure you have to keep turning switch on & off too get pressure built back up.
