My tahoe recently started to stall out while driving. Its acts like it wants to start up again but it does not turn over. I have to let it sit for a bit then it will start up again. I have only had one time where it would just not start at all and I got a "jump", then it started. I have checked all the fused in the interior fuse box and the exterior one in the engine bay. The truck will run fine for a while then it will act up like this, then it goes back to normal. I have read some posts from others with tahoes, and I am leaning towards the fuel pump in the tank. Is there any tricks to check if it is the fuel pump?
I have recently replaced the battery, I just replaced the spark plugs 4 days ago. It has had it's routine maintenance with the oild change and filters. Any help would be appreciated.

Well if anyone is interested, I replaced the fuel pump on the tahoe, that was about 2 months ago. But now it is doing pretty much the same thing. The only difference is I can now hear the fuel pump turn on when I turn the key. I have checked the battery, cables, grounds.

Is there something else that I might need to check just to make sure. I am now thinking something electrical, or a solenoid is going bad. Any help would be appreciated.

It might be the fuel pressure regulator. My brother has a '99 Tahoe. Last year he had problems where it wouldn't start once in a while and it stalled a few times. We checked everything possible and couldn't find anything wrong. This went on for 4-5 months. It hasn't happened again since last August, go figure. I would check the fuel system but these problems that happen occasionally are hard to figure out.

Well now my tahoe seems to be running fine. "Knock on wood"

Well if anyone is interested, about a two months ago it did the same thing again as I mentioned before, but this time my brakes also went out on my. It was a scarry feeling having no brakes. What ended up being was a vaccume valve on my master cylinder that goes from the master cylinder to the engine. It had a crack in it and every so often whe it would move from the truck turning or something it would catch a good amount of air and stall out the engine. I thought this was bogus at first but I started the truck with the old valve and I held it together to seal the crack. As soon as I released and let the crack open my engine started to stall out. I went to the part store picked one up for 2.50 plus tax and everything seems to be doing well. I still have not replaced the fuel pressure regulator, but it might not be a bad idea to do so since I have replaced just about everything related to the fuel system delivery. I wil keep posting if there are any symptoms.
