My 92 blazer with the 4.3 stalls out going down the road. If i let it sit for about 10 min it will start and run a couple of mins and die again. I replaced the fuel filter, made no differance. If I keep the rpms high it will stay running but miss off and on. Thank you for any advise.
Also if I get it started and let it idle, it will run a couple of mins, sputter and die. It seems to run longer when its cold.
