Engine shut off while driving

We were driving our car down the road and it just quit running. We did have to replace the battery, because it was bad. The codes that came up on the car showed camshaft position sensor and O2 sensor needed replaced, which we did along with the crankshaft sensor. We just bought sensors at local automotive store. We took alternator off and had it checked, which showed it was good. We have checked most of the fuses and relays. When we start the car you can hear fuel pump engage. We checked to see if we were getting fuel on one line and we did. We did the security reset, since we changed battery. We have cleared the codes and they still are showing O2 sensor and camshaft sensor. My son tested for spark by pulling plug and checking for spark and compression and said we had both. I have a lot of your discussion on this topic and we have tried all of these this things so far. Is there anything else we should check and any advice to what else we should try next? Thanks
