We bought this 2002 Suburban 1500 about a year ago and love it especially for road trips. The truck recently started to occasionally stahl after about 30-45 minutes of driving at random lights and stop signs. I've tried to fix the problem by first cleaning the throttle body but NO change, then I changed the fuel filter and NO change , fuel pump (cut a hole in the floor, super easy) NO change, fuel regulator NO change, and MAS and still NO change. Most of the time it cranks right back up as if we just got in the car and NO check engine light so far but lately its starting to get a little tougher to crank back up. Like I said earlier there has been NO check engine light but my wife just called me and said it stalled again but this time the Check Engine light came on.
