If you have good spark then it's most likely a fuel issue, anything off of idle is dealing with the main jet and metering needle, clean jet and check needle for excessive wear.

Check the fuel flow through the tank valve. There are screens inside the tank that may be blocked and restricting flow.

The 3000 mule I have worked on has a coil, wire which screws into the coil and spark plug boot.
Do you have power and ground connection at coil.
You said you replaced coil did the wire and spark plug boot get replaced also.
If there is any question about the connection between the coil, wire and boot you might try removing the coil, wire and boot from back cylinder and placing on front. Swap them and see if you loose spark on rear plug after swapping.
Just a thought.
