Just Cuts Off

2008 4.0 While driving it just cuts off. Notice that it happens 90% of the time when I’m turning to the right. Sounds crazy. I know. Have any ideas?
Has 131,000 miles
Only had it a couple of months.
I’ve only changed brakes and oil to synthetic.
Thanks

Might be clock spring or wiring in steering column, ignition switch, also could be the fuel pump driver module, it corrodes and rots causing all sorts of havoc...

Interesting I had same problem only turning left. It was driving me nuts. I have a 2001 so fuel delivery and return system is different from your 2008 however after considering all the possibilities I focused on the ignition coil and wires and re-set the on board computer per (youtube video) and switched the fuel pump relay with another in the refuse box. I fix my 3 year long problem. Seems the Sport Trac has a little difficulty in a power curve needed to turn left or right. In my case left. I remember "Turning Shudder" was an issue Ford was unable to fix during early years of Sport-Trac manufacturing with the power steering. Seems extra engine power is needed whether fuel or spark anyway I replace my coil pack and ignition wires and haven't had a problem sense.
