Engine Mechanical problem
1996 Ford F350 V8 Two Wheel Drive Automatic 55000 miles

This is a 24 foot RV on an F350 chassis. Engine sputters and stalls in hot waether on long drives. It is not overheating. After letting it cool for 15-20 minutes, it starts up and runs fine. We found that if I block the air intake, it will start up immediately. I have been told it is vapor lock. Engine is a 7.5L fuel injected. What do I do?
