Rode fine for about 8km, got to a red light, died. Tried to start and only got a click from under the seat. Pushed it off the road onto the sidewalk, waited a few minutes, clicked the starter again and it started idled and revved fine. As soon as I moved it about 5 feet and got ready to get on the road it died again. MotoLimo towed it home for me, when I got home I hooked it up to a multimeter which read 17.5-18.3v with the bike turned off. While cranking the starter it would drop to 15 then go back up to 17.5-18.3v. Hoping that my multimeter is not broken, ideas?

Replace the battery in your meter. Low battery could potentially give high readings.
IIRC the '99 VFR got a bigger heat sink, for the reg/rec.

R/R problems are not uncommon on the VFR. There are all sorts of solutions out there; OEM replacement, OEM upgrade, new wiring harness, R/R upgrade.
I went with the R/R upgrade and removed the connectors from the wiring harness.
I used the SHINDENGEN FH0122AA R/R. It's still a shunt type regulator, but the MOSFET switching means it generates much less heat in the R/R. It also has much improved regulation.
If you're handy with a soldering iron, you can install one of these for a little under $150.
I had the over-Voltage issue on one of my bikes, batteries are quickly damaged by overcharging.
Yes, the regulator can be the root cause of the bike dying, then restart a few minutes later. Unfortunately, it means the battery is probably cooked. The computer will have shut-down on over Voltage. The cool down period allowed the battery Voltage to drop a bit, the restart pulled it down a bit more, allowing the bike to run. But, probably only for a short time till the problem arose again.

I got an upgraded Reg/Rec and VFR harness (VFRness) for my 5th gen. Good mod for our bikes.

Another common problem. I would recommend a vfrness from tightwad over on vfrdiscussion. By all accounts it works and no more issues with burnt out wires. Tell him Gary sent ya
oops sorry slowbird lol
