Ford Focus doesn't like the heat.?

Question

When the car is baking in the sun it starts having gasoline problems. The car acts like it is running out of gas. There are NO symptoms when it is nice and chilly out (75 or cooler). The problem is not dependent on my driving style. It will do this while going 70 on a freeway or just going though town.

The radiator seems to be working fine because both the intake and output hoses are hot and the thermometer in the dash reads cold when you start the car and slowly rises to the middle where it stays.
I have used 2 bottles of Fuel Injector Cleaner in the past 40 gallons.
I have replaces the fuel filter and fuel pump out of desperation.
The battery was replaced.
The alternator works great (14.5V)
The spark plugs have just been replaced.

I need to drive back to MN from Portland OR and my car will not drive in the heat of Montana. Please help me troubleshoot this car.

Looks like a gas vapor lock. Since the fuel pump is in the tank (assumption), check the piping for local overheating, such as running close to a hot engine or exhaust component. Try to put a wet rag on the hot spot and see if that changes the situation. Also, any inverted-U shaped spot is at risk as the vapor tends to raise above liquid.
Takes some patience and trial-and-error.
An almost full tank may help keep the recirculating fuel cool and reduce the effect.

The Ford heated monitors do no longer reason too a lot of a undertaking. it incredibly is the steel UV shielding layer in some glass (looks pink in specific lights fixtures...Renault use it a lot) that blocks the GPS sign.
