I know this same type of post has shown up a thousand times, but I've been reading through many of them, and don't seem to fit my same circumstances. Been having nothing but issues on my bike these last few months. The problem is intermittent enough that I think I got it fixed, only to come back again. It will seem to run fine for a while, but then randomly start sputtering at throttle (turning on the choke sometimes helps, but doesn't seem to "fix" it, and it can still die). A month ago it started happening more, and I noticed that after it died, the fuel pump kept clicking even after turning the key on 7 or 8 times. I pulled out the carbs and cleaned them all up, swapped out the fuel pump and fuel filter, and put it all together again. Seemed to be running fine until yesterday, I rode about 60 miles (most highway) with nary an issue, and when i was about a mile from my stopping point (last 5 miles or so were city riding), it died on me while giving it some throttle. I turned on/off the key to see if the pump would keep clicking, and it did not. I ended up having to wait a couple minutes, turn on the choke, and limped it to my destination. After being parked for an hour I thought it would have no issues, but right away it was doing the same thing. I thought it might be a low gas issue (was close to when the fuel light would come on, but when I first had issues an hour or so prior I flipped on the "reserve" switch to rule that out as an issue. I got it to a gas station and put about 3 gallons in. It does feel like it's running out of fuel when it does it, which is why i replaced the fuel pump at first. It seems to happen more when it's been running for a while at operating temps, but it has happened a couple times right when i started it up. I've run seafoam through it, and looking in the gas tank it looks surprisingly clean. In the old fuel filter no buildup or anything on it. When I drained the bowls nothing came out except gas. My bike has a stage 7, and these problems started after I installed the vboost butterfly valves (but not right after; just stating the last "big" thing I did to the bike). I was wanting the valves on there for tuning, as well as I was going to experiment having them open at a lower RPM. I've tried leaving them open completely (and disconnecting so they don't even operate) and problems still happen, so don't think it's related. I also did the "crimp fix" a little while ago. It doesn't seem to have a charging issue, but was in the mood to tinker so thought I'd go ahead and do it. It seems to hold a charge as well, since I had it parked for a couple months and it started right up.
