cummins cm2350 code 1141

[Cjhill954]

I have one truck a 2015 prostar. About once a year after an complete engine service the trucks next trip gets a 1141. The code comes and goes the next morning when i check it the code is inactive and does not have a miss. The driver complains on his trip the light comes on and off. I dont believe its actually the injector any one have any ideas.
