Excursion stalling / not cranking
Have a 2000 excursion with 6.8 litre. My wife drove about 30 miles today and engine stalled at freeway offramp. Was able to pull into parking lot and it died.
Engine would not turn over at all making clicking noise like dead battery. I was able to get to truck about 1 hour later and it started up fine. Drove home(30 miles) no problem. Cleaned battery posts and cables. Checked battery and charging system-no problems. Unable to pull codes as OBD fuse, #3 ,was blown. Replaced fuse, linked and no codes given. Any thoughts as to possible problems? I hate to leave wife with unreliable vehicle--Thanks---
Second I presume that you did not have to jump start the vehicle; so I think that you might have water or trash in your fuel tank. Water could accumulate in the tank, try putting a bottle of water absorber in the tank with some good fuel and see if the problem goes away. The next step would be to change out the fuel filters. I hope this helps. If it does not please give more details and maybe someone else can be of more help. We have a bunch of very knowledgeable members who might be able to help you more.

subfitter, I would check or even replace both of your battery cables. Cheap enough and internal shorts/cracks etrc. are more than likely the cause of the no start condition and maybe even the stalling.
After sitting the voltage recovered and you restarted it.
I'd put the battery on a slow charge over night as the alternator maintaines battery voltage and doesn't charge the system when heaters , lights , acccessories are taking away from any posible battery recovery.
Change your fuel filter , check to make sure air filter is clean and not wet (snow clogged) and fill up with good fuel.
Good-luck, If momma ain't happy we all know you won't be.

I am more accustomed to read about diesel engines referred to by how many liters not gas here in the FTE and my brain locked up.Subfitter, Let us know what you did to fix it or if you need more advice.
