Check your operators manual. You can download it for free from Deers website if you don’t have it. Manual says lift the cargo box. I’d look in these areas

What do you mean by Checking the grounds?

There will be wires that are fastened to the chassis or engine or negative battery post. A weak ground can cause all sorts of issues. Your pictures show a lot of corrosion and dirt. What kind of environment is this operated in?
First thing I would do is change out the spark plugs and see if that clears up your issue. Then move on to the coils. Troubleshooting electrical issues over the internet with someone lacking knowledge of how these systems work can be difficult.
