Mine was doing the same thing, changed the crank sensor and no more problems for the past month.

Its better to confirm before throwing money at the problem.

With it in that condition, I would have replaced it anyway to prevent it becoming a problem even if it wasn't causing the symptoms.

Truck now has ~60 miles on it since replacing the sensor, have noticed a smoother idle and no misfires or cutouts since. Will still be keeping an eye on it but I'm confident it's fixed.
