my car turns off when on sudden changes of directions, (left right and stop)

[KB7]

on hard turns the car shuts off randomly, when i stop my car suddenly, and i mean SUDDENLY, the car shuts off darn near 95% of the time.

im pretty sure i know the main reasons this can happen
1, bad grounds
2, oil pressure droppage
3, loss off fuel pickup in tank, -- doubtful
4, oil pick up could be faulty

here are the details of my motor.
automatic, f22a1,
225,000 miles on the motor, which was rebuilt 15,000 miles ago.
autozone oil pump at time of rebuild

synthetic oil since rebuild, only have ever leaked out of spark plug tubes at different times since the rebuild

new fuel pump and ignition coil from autozone around 10,000 miles ago
at this time i had checked the main relay, with an autozone "rental" of a new relay, this being said my main relay has bee in my car for 90,000 miles atleast, (since i have had the car)

autozone oil sending unit about 8,000 miles ago
new fuel filter about 8,000 miles ago

i am not sure if it is related but my auto transmission leaks from the case, a slow but steady leak

i did relocate the battery to the trunk so i will be thoroughly checking my grounds

i am far from being an informed person on motors, so i am asking here to find out if i should add things to my check list

i did a title search for car shuts off
it only found this similar thread [car shuts off when stopping quickly ] with no answers

thanks for all replies
and happy holidays

car turning off on turns reply

is it when your trying to beat an orange stop lite turn or just regular turning? did you have to use hard braking when your making a turn?

[KB7]

no, im not always stopping sudenly, when i need to stop suddenly, for any reason i may need to, i notice the car shuts off when i brake hard
and i NEVER try to beat turn lights, someone did that to me 2 years ago and totalled my car

the hard turns are basically whenever we, (my friend and i)make a tweak in the suspension, and we are testing to see if i like the tweak. i know its not a cordial thing to do, but we stick to abandoned parking lots 95% of the time, sorry about the other times though.

and i dont brake hard during turns, that is never a good idea
these are all seperate direction changes.
either turning left
turning right,
or just stopping,
never a combination

How long does it take to start back up?
Walk us through the start up process if it's not normal.

Just drop to neutral and turn the key. I have never had a problem starting the car. Turns over a moment before I even turn the key.

I'm pretty sure I can easily pinpoint the problem, I would like to know what else if not on my list of possibilities, should I also look at.

I looked in my trunk, and I just noticed that my plastic tools chest sits right on top of my battery ground. That might be my problem right there,

check the cat, my car would do sorta that. its prob clogged. it may not always show a code but try to see if it will throw a code by checking. im pretty sure it will be just a code 41. after i replaced mine it stopped. and this happened after i swapped my engine. i would bet thats it.

editrob sounds stupid but i didnt believe it till it was really cold and it threw a code and it was a 41.

Check all battery and ground connections. Make sure all are clean and tight, and that no wires are exposed where they shouldn't be. The car randomly cutting out could be related to that. ESPECIALLY if your battery isn't securely tied down.

I have an Optima battery, not tied down securely, and the posts are a bit thinner than those on a standard battery. My cables were loose at one point, and my car would turn off any time I did something to shift the battery.
I also had a snapped fender ground that would separate on turns (again, due to the unsecured battery), which would result in my lights flickering and radio resetting. It was never enough to make the car shut off, though it's possible that it could have done so.
