Bike starting then stalling

[njchopper87]

Just as the title says, I was able to start the bike this morning no problem. I let it idle for a few with the choke on, and then took off. It stalled about 30 feet from my house and just popped a lot. I noticed some popping the other day and just shrugged it off because I thought I didn't idle it long enough. Anyway, I tried starting it again without the choke and it started then stalled immediately. I then waited for a few minutes and tried again. Now it didn't even start. I tried with the choke and same result. I walked it back to my house and let it sit for about 10-15 mins and tried starting w/o choke. Nada, then with and it would start and idle no problem. Then when I went to get on it it went to a low idle and it popped a couple times.

I'm about to try some fresh gas when I get back from class, but I don't think that explains the popping.. Any thoughts?
