Engine cutting out
Here is my problem, the engine cuts out like a switch is being flipped off and back on. It does it at idle, when accelerating or driving at a steady speed. I replaced the fuel filter and spark plugs. I have checked the plug wires,fuel pressure(48 psi at idle and 53 psi turning the key on),coils(cleaned the contacts) and cleaned the air flow sensor. I cleaned up the ground under the hood and the ground by the battery. Nothing else blinks or shuts off when it does this.

Typically the 2000'* don't suffer battery cable issues. While it is always a good free check, it'* not typical.
Your symptoms sound very standard for a crank sensor beginning to fail. The downside is they are intermittent and frequently don't throw any codes. If you get any codes for crank/18X/3X or the car starting in gear etc, that would point directly to the crank sensor. That'* the only way our cars will start in gear w/o us turning a key or manually jumping the starter. And the key would require the car to be in P or N to start.

The balancer ir relatively easy as long as you have a puller with three M6 x 1.00 x 75-85mm bolts on hand. These bolts are not typically part of a puller kit. Without them, you'll hate yourself when trying to pull a balancer. With them..it'* quick and easy. The sensor overall is cake to replace. Just have the bolts ahead of time.
Technically you would want a case/crank variation learn after doing the procedure, however 99% of mechanics don't do them as long as the car runs well.
