Is the Malfunction Indicator Light showing?
Have you checked the spark plugs and related components? Something might have come loose.

Did you check for trouble codes?
If you keep guessing what could be the problem, you are going for a long and rough ride which could be costly as well.

Recheck the cranksensor wires. When routing them, there are times whereby they gets too close to belts and other moving parts and this can result in the wires getting damaged.

Did the MIL indicate at any time when the problem occurred?
Was the fuel pressure checked?
