Hi Mx6 owner.,
I recently had a Mx6 but had to sell it because we are expecting a baby
within a day or two

I envey you as they are a great car
but to get to your questioin they do have a fault with that model and can
be a real expence if you dont shop around. Normally when the car stalls
the computer will not let it restart for 5-10 mins if it restarts staight away
it may be something else like fuel related ie pump filter
I called mazda and they wanted $3000 australian to fix the problem
so I called a few wreckers who which they assured me it was a common promblem and they had reconditioned ones for $400 presto it was fixed
and i stopped stalling on the freeway.
:alien: :alien: :frog:
I hope this fixes your promblem
good luck pipe:smoka:
