Intermitently stalls while stopping or even when speeding up. Starts right back up and runs fine.

I would look at fuel pressure, check the egr valve for sticking open or a idle air control motor failure.

When speeding up I thought it was the transmission at first, it will act like it stalls then keeps going, as if I turned off and on the key. It stalls or hicccups about once a week

I would start with basic checks first to verify the basics.
