This situation depends on police reports and insurance. If the vehicle that did the cutting off left the scene and there are no witnesses then this is hard to prove. if the driver that was cut off was given a ticket then a court may have to sort out who is considered At Fault.
Your fuel relay is faulty
adjust your carb so it will keep the fuel up
It means the car is overheating.
Perhaps a vacuum leak at the power brake booster or the check valve on the booster.

car cuts off
car starts but when i put it in gear it stop

Could be a bad fuse... or another alarm went off near your car.
