Fuel Injected cart

I have a 2012 YDRAX2 fuel injected cart that is giving me some problems. It has developed a hesitation (often very distinct as in not running) at almost any acceleration - initial, from stop, during drive. I saw some of this in the summer but it seemed to go away with the addition of Sea Foam. I then left the cart sit for four months when I left Florida for Michigan and just recently returned.

When I got back to Florida last week the cart really struggled to get going and ran very rough. I added Sea Foam and it did get slightly better, so I changed the plug. Sometime it runs pretty good and other times it still hesitates very badly upon acceleration. There are times when I really need to play with the pedal to get it to go at all. It appears to smooth out after running a bit but it still hesitates or stalls off and on. I pulled the fuel pump and checked the filter but I'm really unfamiliar with this type of filter and have not changed it out yet - not even sure where to get one. I checked every connection, in case it is electrical, but everything seems fine. Very frustrating in that I can't tell if it is truly fuel related, electrical or mechanical.

I would think that the fact that fuel additives seem to help make it seem fuel related. I also seem to smell gas when I'm driving and the air box is often wet with gas when I pull the air filter.
