2001 that shuts off after it starts has 200,000 miles on it

Could be ignition trouble or maybe you need a new starter.

It sounds like you need a new fuel pump resistor.

And it could be your antitheft system shutting it down. Actually there's a lot of guessing going on here. What you really need is a mechanic to properly diagnose it.

If it will stay running while you hold the gas pedal down then its probably either a dirty throttle plate or dirty/faulty idle air control valve. I would check the idle air control valve first cause it will probably end up being your problem.

Delete the space between (- 7) should look (-7) for address to work. Sorry iPad issues again.

it was the key thanks

The key you where using was not the original???

yes it wasnt ,, it was a copy from Ace but i did have her tape the spare to the dash and now the copies work

If you would've stated this at the start of all of this, the diagnosis could have very simple and straight forward instead of all the other possibilities. Glad it's taken care of now.

My Pontiac grand Prix supercharge dies after a while it will crank back on and shuts off again i already replaced the maf sensor the crankshaft position sensor and still doing same thing
