Anyone else had a problem with RS stalling on a hot day? This has been ongoing whenever we have hot weather, yet Ford can’t find a fault.
It does it every time I start it, even after a 30 min journey, and a 5 min stop....
It’s bloody embarrassing!

Battery maybe? Our 48lb battery is a giant pile of ****. I have never had problems starting my car, even when it's over 100 outside.

How hot are we talking about? Just did a track day that peaked at 108 F and no issues.

Definitely not battery, it literally is only on hot days....this week is been a nightmare, today because it’s cooled down, it will be fine.

Any CEL that comes up? Temp gauge pegged on high?

Fuel delivery issue? Air Intake issue?

Have not had any issues on mine (knock on wood)

Here's a few more other possibilities: Camshaft Position Sensor. That'll come with a code P034. If the dealer couldn't replicate, this isn't it.

Idle Air Control valve is sticking. P0505

Possible vacuum leak?

That's all I got given mentioned symptom.
