4010 Trans Mule loss of Power

Anyone have any ideas on why I lose power on my 2009 4010 Trans Mule. It starts up fine runs good till I climb a hill and slowly lose power. I shut it off for a few minutes and it runs fine again for a bit. I have replaced and cleaned a lot of parts on it but still the same thing. I have replaced the spark plugs, removed and cleaned the throttle body, new fuel pump and filter, cleaned the fuel tank, rebuilt the secondary clutch. Running out of ideas.
Hi.

I´ve a Mule 4010 2014. The same issue, lose power uphills. I decided to change both coils for OEM ones. Also, replace fuses and clean electrical connectors. After this, the problem was solved. Before this I changed the fuel pump, cleaned the throttle body, changed spark plugs and nothing.

I hope this will be usefully.
