I have a 2018 TW450 that runs fine on flat ground but dies out when under load going uphill. Changed the gas filter and spark plug with same results. Letting it set for a few minutes it will run until it hits a incline. Belt is not slipping, but the engine just dies out and doesn't even want to run in neutral. Any ideas as to what I can try is appreciated in advance. Also only run non-ethanol for fuel.

All mid 2008 through 2014 Polaris RZR 800 series have a big problem with the rear differential pinion nut backing off, allowing the pinion gear to shoot into the rear differential, destroying the rear differential. This has happened with machines with as little as less than 100 miles on them! Reports indicate that there are no problems, nor warnings, until the rear differential grenades, locking the rear axles solid! This requires the machine to be lifted onto a trailer, to be transported for rear differential replacement, as it destroys the case. After failure, rear differential replacement can be quite expensive: labor alone can run from $800-$1200 and a new OEM Spicer rear diff, if you can find one, can run from $1700-$2500! So, if you own any Polaris RZR 800 series between the years of 2008-2014, I recommend that you do this repair before further use of your machine. personally, I have grounded my machine until it can be done. Please check the online post for your own awareness.

I am about 6 months in to owning my 520. It is used mainly to run back and forth to our barn and shop. Occasionally, I run it up and down a few fairly steep hills on the property. One day, as I was going up one of the hills, the motor started sputtering and a tremendous amount of smoke was coming out of the exhaust. I was near the top and it made it (sputtering) up. Once back on the flat, I made it home. I loaded it on the trailer and took it back to the dealer. They said they checked everything out and found no issues. Over the next month or so, I only had occasion to go up hills once or twice with no issue. Then one day, again as I was going up a hill, the engine sputtered, giant plume of white smoke and then the engine died. 30 seconds later, started up and made it to the top. Repeated the route (down and up) and the same thing happened again. Called the dealer and their head of service said he would come out and wanted to see it first hand. He came out a few days later and repeated the route several time and it never happened with him in it. I had videoed the whole thing on one of the times it happened to me, but since it happens intermittently, could not produce it when he was here. I told him that I had checked the temperature, the oil level and the antifreeze level after each occurrence and they were normal. I asked him to call Kubota and ask what the possibilities were and that I am not fond of it dying on the hill and blowing the smoke and I didn't want to wait until something catastrophic happened to figure it out. When I followed up, they had no answers (which doesn't exactly please me). Any ideas? The attached photo was the start of the smoking. Didn't know how to upload the video of the whole thing, but it fogged the whole area.
