89 blazer will start then stall
 

It will start then stall. start, run a few seconds then stall. It started about a 2 weeks ago and it only gets worse from there. It use to take 5 minutes to get it to stay running.then it was 10 minutes then 20 minustes and this morning it was 30 minutes to get it to start and stay running. i have no idea what to do. .
I have read through the other post and have cheked the fuel pump which is fine. next i haver changed out the rotor cap and button. with spark plugs and wires. the Fuel relay is good and the throttle body is still good. any ideas thanks.

When you have a question it's always helpful to enter your vehicle info either in your post or with your signature.
I'm thinking that you may have a problem with the ignition module. I don't know what they're worth in the USA, but you're local Autozone may have a tester.
