I have a 1998 Boxster 2.5L and have owned it faithfully for nearly 100,000 Kms. It now has 160K on it. It nearly left me stranded for the first time recently.

Here is the issue:
The car starts perfectly when it is cold. It usually only requires a few revolutions of the starter for the engine to fire.

Upon getting the car to full running tempurature and shutting the engine off -leaving the vehicle for 1 hour or 2, the engine will not restart when wanting to continue my trip. The engine is around 40-50 degrees at this stage, and I could keep turning over the engine until the battery dies (seemingly) with no response from the engine. Letting it cool further results in a car that will start.

Initially I thought it may be a fuel pump or a fuel pressure regulator that was on its last legs, but reading up on some forums it seems that it may actually be a crank position sesor or cam position sensor.

Has anyone experienced these symptoms and fixed it successfully?

Many thanks!
