What would cause this car to cut off and not restart. Oil is good and so is battery. Alternator is good. Coils and Plugs are new and work. When I try to start the car the starter is spinning and so is the alternator pulley and belt. The timing belt is not spinning at all. and the engine is not turning over. Could this be cause by the fly wheel? Any thoughts on where I should begin?

Your statements are against each other.
,,When I try to start the car the starter is spinning and so is the alternator pulley and belt''
,,The timing belt is not spinning at all. and the engine is not turning over.''
The crank shaft has to turn if the alternator belt and pulley is spinning, so I don't understand your statement about the engine is not turning over???
If the flywheel is damaged and the starter won't be able to turn the engine there should be nothing that could turn at the front at all.
If the timing belt won't turn while the engine is cranking that means bent valves, serious damage. In this condition the engine turns over, spins the accessories pulleys or sometimes locks up - depends on the damage to the valves.

Thanks Zee. Sorry for the confusion. It seems that the altenator pulley is spinning when I try to crank. The engine makes a whining noise but when you check the timing belt it is not spinning and it's not cranking. Pardon my ignorance and please correct me if im wrong. My guess is that if the starter was not spinning the alternator would not spin. I am very much thankful for your insight. Is there a posibility that it may also be a loose ground wire.

Let's clear something:
cranking = the starter spins the engine, the crank shaft is turning, also called "spinning" In this condition the accessories (A/C compressor, alternator, steering pump..) attached by a belt to the crank pulley are also spinning.
starting = the cranking engine is received all the necessary inputs, like fuel, ignition, start authorization and start to run on a specific RPM.
I guess your car cranks (spins) but would not start.
Unfortunately I think in your case there is a problem with the timing belt. I'd remove the front cover and inspect all the timing components. On the 1.8T engines I have seen failed cam chains (connects the 2 cams in the back) which breaks and james -due to a bad tensioner - and lock the cams while the crank shaft still spins, causing a serious damage to the valve train.
Anyway, the loss of the cam timing - being an interference engine - will cause a serious engine damage which requires a major tear down and parts replacement. I'd suggest to find a reputable VW specialist in your area who had done this type of repair and familiar with it.
Could you tell us how many miles are in the car? Was the timing belt ever replaced? Was the car maintained well, all oil changes with the approved synthetic oils, etc..?

THE TIMING BELT HAS A PROBLEM AN IT SOUNDS LIKE ITS NOT TURNING THE CAM. REMOVE THE OIL CAP AND HAVE SOMEONE TURN THE MOTOR OVER SEE IF THE VALVES ARE MOVING IF THERE NOT DISASSEMBLE TIMING BELT OR I WILL LET ME KNOW. BRETT

not good 1.8 t motors ARE interference motors timing belt is broken . your motor is done
