Q: Warning lights come on and van stops accelerating

At various times, the traction control warning light comes on my van’s instrument panel while driving. Then my van stops accelerating and then loses power steering and also the brakes; then it stalls. The ABS and oil lights both come on. I then have to stop, turn it off, and then restart it; after that, it operates normally. I have taken it into the dealership many times but they could not duplicate the problem. Even a Ford investigator test drove it and it would not occur for him either. What do you advise that I can do to find someone who can fix my van?
