Engine cuts out on very hot days Bill Anderson 3-9-11  
I have a 1992 24ft Minnie motor home E350 chassis (approx 45000 miles) with Ford 460v8 EFI engine that stops running after driving in very hot weather with air on and at speed of 50 to 65 usually on major highways,in traffic and always at an inopportune time. So far it will start up only after cooling off for about half an hour but this should not happen.
Doesn't always happen,but is scary trying to pull over in major traffic. Would like to hear a fix for this problem. Have taken it to mechanics, they said they cant fix an intermitent problem. This is unacceptable.

You have to figure this out.
It means the next time it quits you have to check to see if it has spark.
Then fuel pressure.
If you don't know how to do this get a knowlegable friend to show you.
It could be:
Bad ignition box
Bad ignition pickup
Fuel pump
Fuel pump relay
Any # of sensors that get hot and cause a loss of fuel or ignition.
I have seen repairs for this type problem on similar vehicles by putting a small 12 volt fan blowing on the ignition control box.
Good Luck

It could be that its time to take it to the dump. look, lives to short to worry about this. Do as I do,live in your RV. Don't cost to drive or insure it. The kids and wife love it.Yuck Yuck
