So this is the second time I've had this happen. I have a 13 5.0 offroad and both times I made a sharp turn at higher speeds (20-35 mph) and the engine stalled out immediately with the oil pressure light on. I'm not sure if that's because it stalled but why would it stall?

 

Oil pressure light comes on any time the engine stalls because...the engine provides the oil pressure so if it's not rrunning...

 

Describe sharp turn. That's pretty fast to be "sharp turning"

 

Between 25 to 35 mph on a 90 degree turn I drive a bit aggressive at times and manage to keep the rear end planted

 

Probably kicked the fuel pump shutoff that shuts off the fuel pump in case of a rollover.

 

Sounds like fuel starvation as the result of keeping the tank low on fuel.

A fast, sharp turn would slosh the fuel away from the fuel pump's pick-up thereby inducing air into the fuel system or inadequite amount of fuel.

My 2009 Platinum falls on it's face on a fast left hand 90 degree turn, stumbles a second and he traction light shows momentarily. Have yet to get a handle on it and fuel level makes no difference.

 

Slow down?

 

There have been a few reports of this issue with the 5.0 stalling during sharp turns.
No one knows what it is that I'm aware of. Seems to be intermittent with many not even experiencing it ever again.

 

This doesn't seem normal to me. If you think about it, why would Ford engineer a truck that would stall out during an evasive maneuver such as avoiding a potential accident.
Something to be checked out I think.
