I've seen this a lot while searching online. I've never seen a fix though. Essentially setting the cruise control at 35 will cause the engine to stall. Shifting into neutral then turning the key again fires it right back up.

I've also noticed slow throttle response off the line and lunges from a dead stop. Also little to know power on slight speed increases. It's like the sensors don't notice the throttle repositioning. Possible TPS, ECU, Throttle body, Trans issue... who knows... ford sure doesn't.
