Default Lost power while on the freeway!

I was riding to work and I got on the freeway, this is my 3rd time on the freeway and I lost power this time. I was in about 4th gear and at 9-10 rpm when the bike started to slowly go down in rpm. It went down to like 6-7 rpm when I decided to pull over and then when I did the bike died. I tried starting her up but it didn't. So I waited and turned the choke full open and it fired right up. I rode off and it was riding great. What happened the caused my loss of power? Was my shifting wrong?

Did you have to leave the choke on to continue riding? Did it ride fine from that point on?

No, I took off the choke once I got her started again. After she started it rode fine, It sounded normal. I don't know what it can be

make sure you arent getting vapor lock in your gas tank. next time it does that, open up your gas cap and see if it whistles and hisses, sucking air in.

I went to get some lunch right now and it stalled a bit but when I was riding it would like slow down and all of a sudden speed up. It did about two or three times then I smelled gas.

I have been having a similar problem like once a week for the past two months...

I ride a *ton* (like 70-80 mi./day), and every once in a couple weeks, I'll start to lose power (like I'm running out of gas), I'll pull over to the shoulder, wait a minute or two, put on the choke, and it fires right up like there was never a problem! Then it'll run immaculately for a week or two, then happen again.

There's no gas smell on mine, and no mechanic I've taken it to can figure it out (especially since it's so unpredictable and infrequent!!).

Any thoughts?

PS. '98 F3

What kind of gas are you guys running? Does it have ethanol in the gas? I know I can't run gas with the 10% ethanol in it or it makes my Camaro run like crap, so I figured I didn't even want to chance it in the bike. Just a thought.

I always run 91, but usually from different stations. Who has "better/worse" gas?
