So I get a new battery, I go riding the next 3 weekends. The quad sits about 2 weeks. I go to start it , it starts great, the battery is fully charged. I rode it for about a 1/2 hr. The quads then sits for two weeks. I go to start it yesterday the battery is dead? It is a parts unlimited battery and the run button was off the whole time? Is it the battery or the quad?I was able to recharge the battery and start the quad, I will check today if it held a charge

You need to see if there is a draw on the battery with the key off. If the driver in the ECU has been damaged it will cause the fuel pump circut to run continously.

I would do that by disconnecting one of the the terminals and putting the multimeter in between?

Yes the negative of battery. If driver is shot you will be able to feel pump running though.

To clarify you will be checking current draw, using an ammeter in series with the battery and harness. Just like you said, disconnect the battery cable from the battery terminal, and connect the multimeter between the terminal lug of the battery cable, and the battery terminal. Positive or negative does not matter. Make sure your meter is set to read current in Amps.

0.0 amps...now what

You want to use the milliamp scale on your meter instead. The current drain, if any, will likely be a very small number.

I would have the battery load tested. I don't know why but atv batteries have been a crap shoot no matter what brand or size. I have gone back to stockers because they seem to last the longest and they are cheaper. If you run in very cold weather then a larger cca battery would be a good idea but do not assume they will last any longer because of the label or price. Just discharged dead once or overcharged on a car battery charger for a few hours to seriously damage them.

I tried that today dave still 0.00 does auto zone or advanced auto load test batteries for free?

Just take the meter set to volts, leads to +,- . Should be 12v or a bit more. Crank motor over while watching voltmeter. If it drops below 11 volts battery failed load test.
