The Long Island teacher and mom of four killed when her SUV plunged into a backyard pool appears to have suffered a medical episode before the fatal crash, law-enforcement sources told The Post on Sunday.

Allison Rahmani, 40, died Friday when she lost control of her vehicle and drove it into the swimming pool at her family’s Hewlett home.

Police said Rahmani was able to call 911 from the vehicle but could not be saved and died on the way to the hospital.

Sources said police have ruled out foul play in her death and suspect she suffered some kind of medical emergency that led to the horrifying accident.

Rahmani was lovingly remembered Sunday at a funeral service at Boulevard-Riverside Chapels in Hewlett – the same day she was scheduled to leave for a romantic Paris getaway with her husband, Matthew Rahmani, president of Irving Place Minyan Orthodox Synagogue in Woodmere.

Allison, who recently celebrated her 40th birthday, was math coordinator at the Hebrew Academy of the Five Towns in Rockaway.

At her funeral, her heartbroken husband paid tribute to her by reciting the “Eshet Chayil,” or “Woman of Valor,” a wedding prayer grooms traditionally recite to their brides at Jewish weddings.

“We are broken,” her mother, Rachelle Rohde, told mourners during a moving eulogy. “We will never be the same.”
