suzuki 400 4x4

having trouble with my atv. start and ride it just about every day all year long checking the cows and fences and use it as my second set of legs because mine gives out in a little while. the first start of the day it starts good and drive around 500 feet and it dies. first thought it ran out of gas but plenty in the tank. tried again and it starts. may drive another 500 feet and same thing. crank for a few seconds and starts right up. starts every time the rest of the day. done that for 3 days in a row. then the next day I tried twisting the key several times and left it on the on position and it started right up on the first try then it was good for the rest of the day. tried that several times and it started dying again so now I turn it on to the light position and starts and runs like it should. if I forget to turn it all the way to the light position sometimes it will die again sometimes. wondering if it might be the ignition switch. I have ordered a new one for it. thanks
