2000 Mustang GT 4.6. I live in Las Vegas, car runs fine in the morning and in the afternoon when its 100degrees outside car starts fine and run good for 5 to 10 miles then it starts to bog then eventually dies out. No check engine light or code reading. Then after the car cools down again it runs. Anyone else experience this type of problem?
SMH, please help me

 

It almost seems as if the car is over heating but that wasn't in your post. Could be another component of the car getting to hot. Also how long has it been since you changed your plugs they might be old and over heating after it runs for a little bit.
and welcome by the way.
