If you are still having problems, remove the fuel filter & install a new 5/16" fuel line Make it short NO big loops, make sure the vents are not kinked.
ONE of the most important things to check --- Make sure the petcock is working properly. If after doing this you still have problems
check the ignitor. Take a bottle of ice water when it quits, douce the ignitor with water to cool it & see if it starts back up

5/16ths I though it was 1/4 inch thats what on mine. I use the clear blue polyurethane fuel line and its much easier to see the fuel flow thru plus ther is no clamps, easy t slide on but wont come off if you pulled your hardest on it,(like a chinese finger puzzle) Wonta coma offa!

Im a self taught motorcycle mechanic, but have been working cars for years and what this sounds like to me is a spark problem. I would definetly look at the coils, I have had the same problem and checked fuel pressures and filters, but has come down to the coils. If you have on put and inline spark checker on it and run the bike. The checker will have no effect on performance and if you put it on and outside cyl. you can see it while riding. Then when it bogs check to see how strong the spark is.

I would "third" the petcock theory. One of my old Seca's did this. After about 3 minutes of 65 and above, it would do the exact same thing. The first time it happened I was luckily out with a buddy who suggested I turn the petcock to prime. It started right up and ran happily then. The whole time I would ride I would just leave it on prime. Gas mileage never suffered and no gas ever leaked out of the carbs. BUT I WOULD ALWAYS MAKE DAMNED SURE TO TURN IT TO "ON" OR RESERVE WHEN THE BIKE WAS OFF.

Oh hey.... another thing you might try is draining the tank to about 1/4 full and take it up to 65 and above with the gas cap off or just loosely on. It could always be a faulty gas cap vent too that's causing this.
