Make sure you are on the latest firmware.  There was a fuel cut bug in old firmware versions (<5.6.2) where if your injectors were at 100% dutycycle the fuel cut limiter didnt work.  (If this is the case that means you also need to look at your fuel system...)

If you are on relatively recent firmware then we will need a log to see the cause.  Here is how to do that log:  https://www.youtube.com/watch?v=_P1LRANeO4A
