Check the fuel pressure,sounds like may be filter or bad fuel pump

Did you resolve this problem? I am having the same issue. My engine light is on and it is spitting and sputtering. My H3 went dead on me and I was able to coast to safety. There was an error message that read something about the "traction." I looked the error message up and after some research it said it could be my spark plugs need changing. My dad and I changed the spark plugs and found a hole in the breather hose. We replaced the hose. There was some oil that leaked onto one or two of the spark plugs...we cleaned that up as best we could and replaced the hose. Ran fine for a few days and then started spitting and sputtering. I took it to a mechanic. He put seafoam straight through the high pressure fuel line doing a whole induction cleaning service and cleaned the fuel injectors. Again, it ran fine for a few days then started spitting and sputtering again. Can anyone please tell me what experiences they have had to fix this or what you think it might be?
