Sound like a lack of fuel. Since you have replaced most of the ignition parts, I would look at the fuel system next.
Could be a clogged fuel filter, weak fuel pump, or pump relay.

Check your fuel pressure. For fuel injection, it should be 9-12 p.s.i. Your fuel pump is located in the tank. You might have to install an adapter fitting to hook up a pressure gauge. This can be installed inline at the throttle body or at the fuel filter. The fuel filter is mounted on the inside of the frame rail. You might just remove the fuel filter to see if you can blow through it. If you can't blow through it, it is plugged up and that may be your problem. You will need two wrench sizes to disconnect the filter 20mm and 16mm.
