For marriage we consider significators of 2nd (addition to family), 7th (marriage) and 11th (fulfilment of desire) house. For death we consider significators of 2nd (maraka), 7th (maraka) and badhaka. In your case dasa lord Jupiter is in 7th house, lord of 2nd house. Both are maraka stanas. But Jupiter is in the star of Mars, who is in 4th house and Jupiter is in the sub of Mars who signifies Saturn in 3rd house. Even though Jupiter is giving 2nd and 7th significations, as sub lord Mars is signifying 3rd house (life giving house), the death will not occur. The 2nd house gives you finance through your siblings or others. It may be finance or addition to your family. You may go on short journeys to your siblings.
In 2028 – 2031 bhukti lord is Rahu. Rahu is in 6th house, which is a house of sickness. Rahu is in the star of Sun in 4th house and sub of Saturn who signifies Jupiter in 7th house. So 4th house matters will be moved by Rahu with the help of Jupiter. Rahu gives you domestic environment You will face sickness due to 6th house and so you will raise a loan from the people. Unless it is connected to lagna, we can not consider death.
Your lagna is in a fixed sign. So Moon is badhaka stanadhipati. The periods of planets connected to lagna and 2nd & 7th, badhaka are considered to evil effect like death. So it is ruled out that Jupiter period will not give you death.
Next comes Saturn. Saturn is in the star of Jupiter (lord of 2nd in 7th) and sub of Venus who is signifying Mars (lord of Lagna). So Saturn is connected to 2nd, 7th and lagna. In 2042 Moon period is connected. So I advised to take care of health in that period.
