Over the weekend I went to Nevada to play golf and gamble, and on my way home my blazer started bucking and backfiring, and eventually died. Luckily, only blocks from my house. That was about 2:00 p.m. Then at 11:30 p.m. when I left for work, I went outside and it started right up. This happened about three months ago, too and I changed the cap, rotor, plugs, wires, ignition module and had the carb rebuilt. Any one have any ideas what would cause this? Thanks in advance Chrome Won't Get You Home!!!!
