Sounds like the crank sensor going bad... or ign module.

bad relay or senser

today,by the way this is a 3.3 engine,it's losing fire to spark-plugs,when
it cuts off,no warning codes,i'm leaning toward the camshaft sensor.Does
anyone have any tips in changing this sensor,besides a lot of praying?What
tool do u use to make sure u have it the correct distance from the
crankshaft pulley?Thanks for all your helpful replies.

You probably meant crankshaft sensor?
The hardest part is removing the dampner.
You can try wedging in a breaker bar on the nut and tapping the
starter or use a quality impact running 100+ psi.
I use the impact method.
Here is a link to a similar sensor install:
