2005 4.4i, Loses power \ stalls accelerating into tight corners?

[Purplefade]

Hey guys, I am killing time waiting on my wife so I have had no time to do any diagnostic work yet, hoping maybe you guys will give me some ideas that I can dig into once I have the X home and back in the garage.


Right after we left the house my wife said "oh shoot, I left my purse at home", so I whipped it around for a u-turn and as I went into the turn she lost power.. didn't stall, but fell flat on her face, I did a quick lift of the foot and as soon as she settled back down we were off to the races again???


Had this happen to me once before, very long time ago and never happened again so I wrote it off as one of those things... - now it's happened twice inside a few days and is very reproducable - but does not happen in a straight line. If I mat it from a dead dig she goes like madness, no hesitation what so ever, but add a corner, left or right hand, doesn't seem to matter and she's dead, flops over on her face, lift foot, settle down, peddle down and she goes again.


Where to start? Thanks!!
