Got a problem with my 2015 P5. When the engine is fully warmed up, the engine wants to die if you try to sit and idle. Also stalls frequently when it is dropped into gear or when you first step on the gas from a dead stop. I originally thought this was due to water in the fuel. I drained the fuel and replaced with fresh gas that was treated, and I thought the problem was fixed. However on a long ride this weekend the symptoms have returned. Anyone else have experience with this type of issue?
