Ford Ranger 2.2 XLS double cab problems

I have a 2014 Ranger 2.2 xls double cab. When driving, with engine under heavy load, like a mountain pass and then reduces load because of a vehicle that I cannot pass, the following happens. When I pick up speed again, then the engine management light and the traction control light comes on and the engine goes into limp mode. I then just switch of the engine and start it again to reset the lights and limp mode. The problem is that Ford do not know what cause the problem, and do not seem very eager to solve it. They tell me the lights must be on for them to look for the problem, but I cannot let my vehicle idle for a whole weekend if it happens. I have done quite some research on the internet and it looks like if Ford are unable to diagnose problems ot the Rangers, and that the Rangers are plagued by quite a lot of problems. No Ranger for me again
