1995 blazer 4.3 vortec. just turned 200k yesterday.

Long story short i was drive to a christmas party at the in laws and my blazer decided to just loose power. Out of no where RPMs went to 0 and the motor shut off.(i had this same problem with my ZJ and it was the fuel pump) PO said the fuel pump was replaced. i can hear it turn on so there is power. i just changed the plugs when i bought it(like 2 months ago). it turns over but after 2sec's of cranking it. then it makes a puff noise kinda like when an air compresser get full and blows off....

any help would be great. need to get it running asap. thanks

I sold it last year.But yes it worked right off the get go.I had just replaced the plugs and within a week or two the cap took a crap.The guy that bought it still driving around.So I would say yes.Also my son had a blazer with the same setup and had similair problem and it was that cap as well.
