I do not have information for your model, but this is typical of a failing crankshaft position sensor or camshaft position sensor. They often fail by becoming heat-sensitive, then they work again after cooling down for about an hour. While driving, natural air flow keeps those sensors cool. When you stop with a warm engine, the heat migrates up to the sensors and can cause them to fail for a little while.

The place to start is by having the diagnostic fault codes read and recorded. There may be a code set related to one of those sensors.
