Hey Y'all-
I have a 99 Bravada that runs really well for the most part (aside from an intermittent check engine light- vacuum hose that's been replaced). I was driving to work last week and it was cruising along great and smooth at about 70mph then sounded like it backfired through the intake and completely stopped running. The tach stayed up at about 2500 for a few seconds and then died. Prior to this occurrence I've replaced basically every electronic component from the in-tank fuel pump forward. Its not the throttle control sensor or the ICM. I'm obviously hoping that its something easy and cheap- but we all know that it's rarely that way. Any help would be greatly appreciated as I'm stumped and confused. Thanks for your time and assistance
