1999 Chevy Blazer 6 cyl Four Wheel Drive Automatic 160000 miles

i have a 99' chevy blazer v6 4wd and if I don't let it sit and run for a few min after I start it it cuts out and drives really slow for about a min then it's fine. My uncle is a mechanic and he told me he thought it was a fuel filter so I changed it and it hasn't helped. Could you give me your oppinion on what wrong with it? Thanks
