Ika, has it started back? If not, it may be a timing belt/chain broke. If it cranks, it may be a fuel pump, filter, pinched gas lines, or bad fuel injectors. It may be a problem in the ignitions. Spark plugs,coils, wires, distributor, coil pack, dist.cap, If it is not cranking, check ignition fuse. Check battery, wires, and whole charging system. If it is just dying on you and it starts back, it may be a map sensor, idle sensor or throttle sensor possibly. Need a little more info please.
Accessing the knock sensor is not a hard job when the front seats and floor are removed, should take no longer that 2 hours at a dealership. It is a common fault for the knock sensor to fail & will give obvious problems with power. Also, the check engine light should illuminate. Very sorry you have had to spend this kind of money.
