being an owner of a '97 ford class A and having the stall problem several years ago, Heck of a vacation. You can probably search for the fuel pump problem and see myself and several others who have experienced this issue. Anyway, It was the fuel pump, in the fuel tank. It cost around $850.00 about 3-4 years ago. They can do a fuel pressue test at the dealer and let you know if it's the fuel pump. It makes things easier if your tank is empty or as close as possible when they work on it. Get it fixed now, don't wait until your on a trip and you have all kinds of problems and pay more to have it fixed.
