MY CAR WONT ACCELERATE PASSED 30 MPH. WHAT CAN BE THE PROBLEM?

2000 Lincoln Town Car • 160,000 miles

Once I reach 30 mph the car will not accelerate. I hear a humming like its trying however once it make it to 30 mph I have to either slow down to 10 mph or a full stop before I can accelerate again.
