Try setting your gun this way:
With gun empty back the fluid knob all the way out leaving just a few threads engaged. Pull the trigger full open and turn the fluid knob in until it start to lift the trigger. Let off the trigger and then turn the fluid knob another 1/2 turn in.
Tape a piece of 16" masking paper on the wall about 24" long.
With paint in your gun pull the trigger just far enough for the air to come through but no paint. Set your PSI at the gun to Iwata's recommendation range. I would say 32 PSI would be a good place to start with your gun.
Now hold the gun about 6" from the masking paper and pull the trigger full open for one second. I say 1/1000 and then let go. Look at the pattern on the paper, it should be cigar shaped and have full coverage throughout the fan pattern.
If the paint starts to run, turn your fluid knob in 1/2 turn and repeat the 1 second blast.
Remember to keep checking the PSI at the gun and keep it solid at 32 for the time being.
The goal is to get consistent fine droplets of paint throughout the fan pattern. Remember you will be overlapping your spray by at least 50% so there will be twice the amount of paint on your panel than what is on your paper.
This should get you close and you can adjust further based on your speed of spray.
Another thing to do is set a yard stick on a table and move your hand over it pretending to be spraying. You should cover about 12" per second.

Thank you all!! I did have a good cigar pattern but it did run on my test/set up. I will do the practicing this weekend, I work all weekend 12hr shifts so I can do my homework and get ready to paint again next week. I have a little bit of sanding left but got it flat before it hardened too much. I am so grateful I started with the bed which is much more manageable than the body of the truck. I appreciate the help!

I had a few area I sanded through so I reapplied the epoxy to the areas and have wet sanded the entire bed and tailgate with 400. My question is I applied the epoxy Tuesday and wet sanded yesterday. The tech sheets say 5 day window to apply paint, I wont be able to get back to this Monday/Tuesday next week, since I wet sanded everything yesterday would I still have to sand again if outside the 5 day re-coat window?
