5.4 Liter engine lost power hot weather
So Silvan is at the Ford dealer in Prineville waiting for diagnosis. But I think this forum can diagnose it better!
Van has 50000 miles. I was towing about 1000 pounds and it was HOT, maybe 110F. As I was going up a long fairly steep grade, it lost power quickly but not like an off switch. After sitting with engine off for 5 minutes it restarted and had full power for about 1/4 mile. Then I gave up and called a tow truck.
My first though is fuel pump but everybody says it would not restart. Vapor lock? But that's impossible!
The shop is fully booked but they did say they would look at it next week.
Did I mention it was hot?
