    i agree with the key issue, my 200 tahow does that everyone once an while. I would bang on where the key goes and it would start. The security light would be on sometimes.

From what you describe, it sounds like a fule issue, not an igniton issue. Check the fuel pressure at the service port to make sure you're getting the right fuel pressure. Could be your pressure regulator malfunctioning or possibly clogged injectors if you have high mileage on the vehicle.

    It couldn't hurt, but your best place to start is still by checking the fuel pressure to make sure the correct pressure is reaching the injectors.

I have 1999 plymouth voyager. Runs great when its cool outside but stalls an dies when its hot out. Runs good for bout 10-15 min then stalls out an sometimes starts right back up an sometimes takes bout 5...

Sounds like a vapor lock in the fuel line. If the fuel line is a hose, then in summer time, the line , if it is old, will collapse due to vapor lock. This will cause the problem you are describing.

On our 02 tahoe we have changed the fuel pump,fuel filter, wires and plugs and 02 sensor,but when after driving for bout 15 mins it still wants to bog down and sometimes even kill.

Providing your air filter is clean, my guess would be a vacuum leak.With the engine running, pour some soapy water along the intake gaskets and see if it bubbles a lot. Check all vacuum lines by wiggling them when the motor is running, and listen for a hiss.
Check your timing and timing chain.
Egr system.
Faulty ignition coils.
Good luck.

I had similar starting problems with my 99 Tahoe. It turned out to be the anti-theft device was malfunctioning and not recognizing the key so it would turn off the fuel pump and eventually the fuel pump went out too. Since having this replaced ($555.00 with parts and labor at the dealership) I have had no more problems at all with my truck and have actually braved taking it on a 6 hour road trip and had no problems with it leaving me stranded. Since that road trip, I have gone on several more and have full confidence that I will no longer have this be an issue.
