My truck cranks over but it will not start. While I was driving it stalled I waited a while and then I was able to start it and drive home. I replaced the fuel filter, it started up and drove for about half a mile and then it did the same thing. I checked the choke and cleaned with carburetor cleaner, still no start so I replaced the fuel pump which is electric and it still will not start. When I was checking the coil I removed the plug from the coil and plugged it back in and it started. Once again I drove it for about a half a mile then it started running rough I gave it more gas and it ran fine but then it stalled on. Now it will not start.
I have replaced the coil, spark plugs, cap, rotor, fuel filter and fuel pump. Help!

Check resistance of plug wire may be bad, 5000 ohms per foot then check for spark and blown fuses. Finally check relays.
