Was out for a ride with a group last week and it was warm out about 87 . So a couple of times my Ultra stalled cranked over and started back up the last couple of times it did it I had to crank over a few times to get started. I'm beginning to think maybe a vapor lock not sure any help would be great.

Most likely not vapor lock, EFI fuel system is pressurized and the tank is vented.
It could be that the CKP is getting out of parameters, common with age.
Also could be the tank internal fuel line developed a pin hole, that would cause a fuel pressure drop.
