BAD problem and I have seen others with the same problem on line and having problems getting it fixed. What happens is that you start the engine and go for a while and then if you turn the engine off, it will not start again for at least a half an hour. One time it was hooked up towing my 28 foot trailer, which was a nightmare! There was also no power towing uphill and this really created a mess for traffic behind me. Took it to the dealer and they identified the problem as an oil pressure leak and fixed it under warranty so I do not know how much it cost or what exactly they did to repair it. However, this did cure the problem, whereas many others online had been unable to resolve the problem even going to the dealer (but none of their dealers/mechanics had identified the same issue as an oil pressure leak). So, if you get this problem, know that an oil pressure leak is a possible source of the problem.
