While crankshaft position sensors do fail it is very unlikely they will both fail at the same time and engine would run with 1 failed, they also register fault codes if they are faulty. I think it's more likely to be fuel delivery issue, can you hear fuel pump running for couple of seconds when you switch on ignition?
