The 67-year-old Powers died June 22, three weeks after the Republican Party endorsed him for Fossella's seat.
Fossella announced last month that he wouldn't seek re-election. His decision came after a drunken-driving arrest and the revelation that he had fathered a child outside his marriage.
Powers' death has left Republicans looking for a candidate to try to hold their lone seat in New York City's congressional delegation.
Powers was a retired Wall Street executive.
