S205 losing RPM and stalling

[ssrider]

Hi I have a 2007 bobcat S205 with about 2000 hrs. Owned it for a year and had no problems until last night. I was cleaning snow for about 1.5 hours last night in -25*c. Ran perfect for the first 1.5 hours and then started feeling like it was losing power (engine power). I kept running it for a couple minutes and then it really started losing power and rpms. Letting go of controls it still wouldn't rev up. I limped it back to my shop and it died 3 times before I got there. Itwould start right back up no problem after it died. I added a Jerry of fuel that I've had sitting around for a few months before I started clearing, but it ran fine for 1.5 hours? It feels like a fuel issue but at the same time it seemed like it was smoking quite a bit. (I could smell rich diesel exhaust.) Once I got it in the shop I checked air filter, which was fine. Drained the fuel filter, a little **** in it but nothing terrible. Checked all fluid levels, everything good. Also pulled the pickup tube from the tank and everything is good with that as well. Machine didn't throw any codes. I'm kind of lost here. If bad fuel, wouldn't it cause no smoke at all because it would be starving?

In the summer months, a higher paraffin content in diesel is allowed. (at least that's in Europe). If you have used such a fuel, at -25 it has clogged the fuel filter and the lift fuel pump can not pump fuel. In this case, the machine will not smoke. Change the fuel filter and use the winter fuel.
