crank sensor most likely the problem.. classic symphtoms you are describing..

occasionally cam sensor but usually crank

I agree, next time you have this problem try unplugging the crank sensor and plugging it back in. You will find it just under the power steering pump.

Or check to see if you have a fault code reporting it....crank sensor error code 11 if I remember right.
