Car turns off while driving

[kyobibi]

Can you think about exactly what you were doing when it happened?

Accelerating / Backing off / Turning / Idling etc

All sorts:
1st: taking off at lights (thought i had accidentally stalled the car)
2nd: downshifting to stop
3rd: just cruising at 60km/h

hms, could be main relay, but then it would struggle to start.
so i would say ignition switch.
got heavy keys? that hang off the ignition barrel while driving?

Yeah, it doesnt struggle to start at all
No heavy keys or things that hang off the same key chain..
Even tried jiggling it to try and get the car to turn off but nothing happened.

i can tell you right now it is your ignition switch. I had the exact same problem with my car it would all the sudden turn off. It also happen to my sisters accord with the exact same fault. I would sometimes find it hard to start aswell. take notice at your dash the oil light ect will not light up. It is a common problem with hondas

Is the ignition switch expensive to fix?
Is it a mechanic job or an auto electrician job?
