Recommencing the kaffara due to breaking one's fast before sunset

Q: Someone is doing kafaarah for ramadan fast. She is on her fifteenth fast. However when she was on her fifth fast she had broken her fast two minutes before iftaari but she carried on doing her kafaarah. What is the conclusion? Will her kafaraah start again from after that day or does she completely have to start all over again?

Investment scheme

Q: My father joins a profit-sharing business which guarantee a monthly dividend between 15% to 30% for up to 1 year (with no guaranteed principle). My question is, is it permissible for me to market this profit-sharing business and make out a sideline business agreement out of it with my potential client? The agreement shall state that, I shall be the guarantor of the principle amount given for the purpose of the profit-sharing business. In return, the client shall pay me a 3% monthly dividend for the period of 1 year. In the event that the business collapses, I shall be liable to pay back the principle amount to my client.
