My 2012 Can Am Commander out of the blue just started cutting out when it got hot. Everything pointed to a fuel pump which I replaced with a quantum fuel pump and it ran good for awhile. About a month later the UVT started doing the same thing after about 3 miles. I decided to take it to the local dealer and they said the pump wasn’t holding the required pressure. I have since replaced the pump and fuel regulator and now the UVT is very sluggish when I accelerate. Any ideas on what is causing this and possible fixes?
