How to ask for a recommendation letter from a professor after long time? I had worked under a supervisor in 2015 and that year I asked a recommendation letter from him for a Ph.D. He wrote it very well. On 2016, I again asked him for one and he sent me again. Both of the times my application was unsuccessful. This year I had applied for a very prestigious scholarship again and I have been shortlisted. While applying they asked for the name of the referee and they said they will send a request to submit a reference letter to the referee if the applicant is shortlisted. So the scholarship committee already sent the professor a request mail. I did not expect that I will be shortlisted so I did not inform my referees earlier. Now I am confused how to write him an email and ask him if he can write one for me again? The professor is really good and helpful. We did not have any contact these years which made me feel awkward to write him.
Shouldn't be a big deal.  He will likely just send the same one he has on file.  Send him an email and politely ask for the help.  

Dear Professor Y,

Thanks for your kind letters twice before. I am now a second year Ph.D. student at Fantasy University, working on a thesis in widget design.  It is going well--my training from you and the rest of the ESU staff is being put to use.

I have another request, this time for the SooperDuper Fellowship, which will support me financially at FU.  Actually I have already been shortlisted, so chances are good.  

Could you please send copy of your earlier letter to support me with SooperDuper?  Submission details:

Once again, thanks for your kind help.  Would love to stay in contact.

Sincerely,
