I believe I have the same problem as contour dave. I am very interested in the solution.

My engine runs fine until it reaches a certain operating temperature. For example driving for hours on the highway is no problem. Driving in the city and idling around, the engine temperature rises to a certain point and then the sputtering and dying happens. It seems to be running lean and no amount of throttle will keep the engine alive. The car must sit and cool down, from minutes to hours, before it will restart. No CEL, no codes in memory.

As a poor boy fuel pressure test during a stall no start conditon I depressed the schraedder valve and got a good mist of fuel spray. Not sure if that could rule out the fuel pump as a culprit.

All suggestions welcome.
