My blazer just decided one day to sputter till it died like it was out of gas. I have replaced the fuel fliter and fuel pump and new plugs and wires and a gas/injector treatment. It will not stay running. It will fire up then stay running sometimes for a minute or two then sputter and die. I have no idea what is causing this. ; ; i need my vehicle for school. Please help me out.

Do you have a check engine light on ? If so go to your local to parts store and get them to put it on a scanner . ( It's usually Free)

I would check the
Idle Air Control Valve and
check for vacuum leaks .
Check fuel pressure .
Ensure that the ignition timing is correct .
