I have a 98 Mercury Sable, after the inital start of the car and driving for about 20 miles or to my destination and turning the ignition off upon arrival the car will not start back up. If I let it sit for about an hour it will finally crank. We have put new cam position sensor and a coolant temperature sensor on it and still has not fixed it. Can you please help?

Next time this happens don't wait for nothing-Lets do below for a start to determine if its fuel or spark related issue and get back asap.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
