It's getting a code P0106 in my 1997 Plymouth Grand Caravan SE with the 3.8 liter SFI engine.

It shuts off when it is hot outside. If it's very hot outside (above 90 degrees), it simply won't start. It ran great in the winter. On cooler days, it will run a while, then shut off. Waiting a few minutes gets it to start again. Whatever is doing it, seems to be shutting off the fuel flow, because cranking the engine does not make it catch or fire until it is ready.
