Car Starts But Goes Dead Afterwards...

I changed my valve cover gaskets on my '89 L-98 GTA
the other day.Everything I thought went smoothly they came off and went back on.
Now when I start the car it runs for about 30 seconds and goes dead.It ran fine till I changed the valve cover gaskets.Can someone tell me what have I done wrong and how can I fix the problem?
Any help you guys can give me will be appreciated and trust me i need help badly with this problem.Thanks in advance for any help and/or suggestions!

sounds like you have a vacume leak (a bad one) my friend. Make sure all your vacume lines are connected where they should be. I know b/c I have gone through this before and I know how frustrating it is. Do that and your problem should go away.

I will check for vaccum leaks.But I was extra careful not to take
anything apart or loose that did not need to be disconnected.
Thanks for the pointer...

Also check to make sure you didn't pinch a wire or vacuum line under the valve cover.

If you bend those old vacuum lines they break pretty easy.
