My 2001 Suburban 2500 stalls while driving or idling. It completely shuts off, no hesitaions or warnings. More often than not vehicle will turn over stongly but not start for a few minutes after such stall occurs. No codes are stored. No common threads here, can happen at any time: highway driving or at a stoplight. At certain times it will stall for a split second(battery indicator comes on) but vehicle restarts itself. Any Help?? We are usually carrying 4 young kids and worried this is becoming safety hazzard. Thanks.

Have you tried cleaning the trottle body? Or, perhaps, have the battery checked for voltage.

I have the same problem. Did checking the battery work?

My problem started right after a visit to the dealer. I was adamantly warned that my K&N filter is a bad idea and that it can contaminate the air mass flow meter. I was planning on replacing it (very suspicious).

No K&N filter here. Dealer told me my battery terminals were loose and that was the cause. The thing was I had checked the terminals myself before dealer inspected. The more I have been researching this forum; it appears I may have a faulty Crankshaft Position Sensor. I am going roll the dice and have it replaced($92part+labor). Hopefully this will cure the ailment? Will let everyone know if it works.

My K&N filter is causing similar problems with the trottle body.

Thanks to all at AutomotiveForum. 01 'Burb has been running great since Crankshaft Position Sensor was replaced. Dealer gave me a little grief at first but eventially changed sensor at my request for about $200 part+labor.

We are having the same problem with our 01 suburban stalling. How many miles were on yours when this started. Ours is at 92,000 mi. We are going to mention this to our mechanic and see if he is game for checking on this. Thanks for the great info.
