Is this an S-10 Blazer or a K5 Blazer? Big difference. A little more
detail about the vehicle will help a lot.

Ok, that's better... Have you checked anything yet? I'd when you're
trying to start it are you getting a lot of gas fumes out the tailpipe?
Are you getting spark? Gotta be one or the other.

Does it die all at once or start losing power first? Tell us exactly
what happens before it dies.

when i start the blazer it starts with out a problem right at the turn
of the key. but as it worms up it just dies. it doesn't lose power it
just stops and wount start. again till its cool. when its at a idel i
looked at the injects and thr right one had vary litte gas come out.
not as much as the left? other then that i haven't checked anything

Ive seen vehicles act this way when the catalytic converter/muffler
have deteriorated to the point the exhaust is clogged. Easy to check,
drop the exhaust loose from the manifold and crank it. (just went
through this myself, a little "modification" to the converter and all
is well)
