Hello everyone; I just recently purchased a beautiful 2005 limited 6.0L excursion and love it, but I have a peculiar problem.
Forgive me if there is a similar thread I am on my phone and couldn't find any similar occurences.
I have had my engine stall on me when the tires slip, I took it out mudding and once my tires really started spinning the motor shut off. The other times it has shut off is when I did a brake-stand and let off the brakes once the wheels start spinning faster it simply shuts off. it also seems that if i do a small wheel spin it doesn't cut out either.
Any thoughts or opinions will be very appreciated. Thank you

 

That's the auto preserve/save feature build into the 2005 6.0 engines

 

It's been driving me crazy it won't let me unleash the full power I wanted to show off what it could do and it stalled... Very embarrassing.
Is there any way I can go around this failsafe bypass it or maybe a chip will stop it?
Thank you for the solution!

 

I'm kidding, it could be a lot of things. You should post in the 6.0 farther down, or ask Stewart to move this thread to that forum, there are some good guys with great answers their, good luck!

 

Have you changed your 2 fuel filters lately? It's recommended every 10k, fuel delivery?
Or it could be a bad electrical connection, when the engine shifts from the torque a wire/wiring shorting out.

 

Moved.....

 

No i just bought it a few days ago and haven't changed any filters fluids or anything else yet but i will be as soon as I'm back from camp.

 

got enough fuel in it? maybe when your doing your stunts the fuels slow and sticks to the side of the tank or something.

 

Ya i had plenty of fuel it only stalls once the tires really start spinning if i do small burnouts it runs fine. It shows no other symptoms doesnt give any warning its weird.

 

Why are you doing burn-outs in an Excursion?

 

his mpg aint bad enough yet.

 

I have to see what kind of power i am working with! I like to have a little fun with my vehicles. And my dad and his friend wanted to see if it could, can't let em down.

 

16 MPG including gridlock big city traffic small city traffic burnout and 4X4ing and highway driving all combined and hand calculated.

 

How many rpm's when it stalls?

 

I forgot to take note exactly but i know its when it starts to get closer to its redline and I can feel the tires really start spinning is when it shuts off. I haven't pushed it right to its redline though because i don't want to out too much stress on it before engine upgrades.
