my 2000 audi a6 will start just fine and runs until it warms up then suddenly shuts of and will not start for a couple hrs. I changed the fuel pump and the o2 sensors. the car is giving me codes for evap leak and 02 sensors but I changed the 02 sensors any ideas

Crank position sensor??? Not so common that the car suddenly stops when running, but otherwise your symptoms are similar. Search for this issue and read up.

Engine coolant temp sensor? Maybe it runs rich till it warms up, then fails to lean out after warmup. But I doubt it would be sudden. More likely black exhaust smoke and rough running 'till it dies.
