2005 LAND ROVER FREELANDER Engine Problems

I PURCHASED MY CAR IN 2011 FROM A COUNTY AUCTION. I'VE SPENT ALMOST $8,000 ON ENGINE AND ELECTRICAL ISSUES SINCE I'VE BOUGHT IT. HAD A NEW TIMING BELT, SPARK PLUGS AND IGNITION COILS INSTALLED ON 02/02/2015, BUT NOW MY CAR STALLS AND I HAVE GREAT DIFFICULTY PICKING UP SPEED, EVEN WHEN DRIVING ON THE STREET. IF I STOP AT A STOP SIGN, I LITERALLY HAVE TO PUSH THE GAS TO THE FLOOR TO GET MY CAR TO TAKE OFF AND EVEN THEN, IT TAKES FOREVER. THE HIGHEST SPEED MY CAR WILL GO TO NOW IS 30MPH. MY DRIVEWAY IS AT A SLOPE AND I HAD TO PRESS DOWN ON THE GAS TO GET ME CAR TO REVERSE OUT THE DRIVEWAY. *TR

WAS DRIVING DOWN THE ROAD DURING HURRICANE SANDY AND THE CAR SHIFTS (OR LAGS) INTO EXTREMELY LOW GEAR, MAYBE 5-10 MPH. THE SERVICE ENGINE, SERVICE ENGINE SOON, AND OTHER LIGHTS ON DASH CAME ON AND VEHICLE WAS LURCHING. ONCE I ABLE MOVE TO THE SIDE OF THE ROAD, I AM ABLE TO TURN THE VEHICLE OFF, WAIT LESS THAN 5 MINUTES AND TURN BACK ON, STILL DOING SAME THING. LUCKILY FRIENDS HOUSE WAS JUST DOWN THE STREET, AND COP STAYED BEHIND US UNTIL WE GOT THERE. THIS VEHICLE HAD ABOUT 110,000 MILES WHEN WE PURCHASED FROM A PRIVATE PARTY OUT OF STATE - THREE WEEKS AND THREE HUNDRED MILES LATER THE VEHICLE IS NOW DEAD. THESE FREELANDERS ARE NOT DEPENDABLE. I DON'T KNOW WHAT TO DO BECAUSE IT WAS FINE WHEN I BOUGHT IT, AND MECHANIC NOW SAYS IT NEEDS 7,000 WORTH OF WORK!! THIS IS AND WOULD HAVE BEEN...
