Ask a Former Manager for a Reference With an Easy Way to Say No

Draft a polite email asking a former manager to be a job reference for me. Use only the facts below and add no praise, results or details that I did not give.

Manager's name: {{manager_name}}
How we worked together (role, dates, what I did): {{our_work}}
The role I am applying for: {{target_role}}
Date by which they would need to reply: {{reply_date}}
How the reference would be used: {{reference_use}}

If anything is missing, ask me first. Write a subject line and an email of 90 to 130 words that does these things: says who I am and when we worked together; names the role and the reply date; says what the reference would involve, using only what I wrote; makes it easy to say yes or no, with a clear sentence that 'no' or 'not this time' is completely fine; offers to send my resume and the job ad; and asks how they prefer to be contacted.
Do not put words in their mouth, tell them what to say, or pressure them. Then draft a two-sentence reminder that I could send once if they have not replied two days before the date.
