My Dodge will start and runs great till you turn off motor. Once it has been turned off it wont start again for at least an hour or two. It sounds like fuel pump is coming on and we have replaced the crank sensor and the ignition coil. Please help !

Which engine do you have? Have you checked for diagnostic fault codes? Have you checked for spark when it doesn't start?

It is a 5.2 V8 and honestly I just bought it 3 days ago and it had it check engine light on when I bought it. It also had a invoice from O'Reillys where previous owned had light checked the day before I got it. It didnt give me any trouble at the first evening and most of next day but before I had owned it for 24 whole hours it just messed up. We let it sit for a few hours while we drove the 15 miles into town to buy those two parts and when we got home that evening my husband put the igntion coil on and it started right up, we drove around and then turned off at home and tried to start right back up and it wouldnt. That was all yesterday and today when he got home he put the crank sensor on. We let it run in our driveway for about 30 minutees, had killed motor and restarted 4 or 5 times and it did great till we drove to town to get gas, now we are sitting at as station and wont start. My husband say he is not getting a spark.

The fact that the Check Engine light turned on indicates there's a diagnostic fault code stored in the Engine Computer. Most auto parts stores will read the codes for you for free, but Chrysler makes doing that yourself much easier than any other manufacturer. Cycle the ignition switch three times from "off" to "run" within five seconds without cranking the engine, leave it in "run", then watch the codes show up in the odometer display. Holler back with those numbers or you can go here:

The crankshaft position sensor was a good guess but the camshaft position sensor is probably a more likely suspect. It sits in the top of the distributor. Either one often fails by becoming heat-sensitive and they commonly fail during "hot soak". That's where there's no natural air flow while driving to keep them cool and the heat from the stopped engine migrates up to the sensors. it's typical for them to work again when they cool down.
