I have a 60th anniversary R3 always ran fine no issues but I dont ride it that much but I do start it at least once a month.. and keep it on a battery tender.. One day, I went to start it and it wouldnt start.. so I replaced the battery.. the original battery was still in it. so new battery and started it started up fine.. ran for about 5 minuets idleing and died and no start afterwards.. I figured the new battery might not of been fully charged so I charged it up and again nothing. So I figured maybe a bad battery so took the old one back and got another one.. same issue no start.. checked the voltage on the battery and it was fine...now I can hear the fuel pump priming up... but no start.. so I changed the plugs and still no start checked all the fuses all looked good.. so... to see if I had a fuel problem.. I took a old rag soaked with rubbing alchohol and held it up to the intake.. started right up several times.. runs and as soon as I take the rag away stalls out.. so its not getting fuel.. what should I check next? or replace.. fuel relay switch>? what else any help appreciated Thanks

You said that you could hear the fuel pump when you switch on the ignition. That means the pump relay is working. Does the fuel pump keep running or does it shut off when at the pressure limit ? (Try to see if the fuel line is stopped up.) If it starts with a soaked rag on the inlet, then it is a fueling problem.
1st: What is the fuel level in the gas tank ?

Hi Thanks for writing back.. The pump shuts off normally after a few seconds.. the gas tank is full i added more gas to the top.. still same.. yes its a fueling problem... but I dont know where to look next as i assumed its a sensor or something assosiated with the fuel delivery... what other sensors are there if the fuel relay is working that would cause the bike to not start..
There's just too much on the bike controlled electrically to attempt a guess without the proper knowledge and diagnostic equipment. Sensors and electrical components are seldom returnable... and often expensive.
It may or not be electrical. It could be nothing more than starved for fuel. A pinched/kinked fuel line or debris somewhere in the lines or filter screen.
The fuel filter is inside the tank attached to the fuel pump assembly.
Accessed through the bottom of the fuel tank as a complete unit.
It may not be the filter either, but it's something relatively cheap and requires little more than basic mechanical skills if you're still trying to eliminate parts.
There are several how-to videos available with an engine search on replacing the R3's fuel filter.
The link below is a schematic and parts of your bike. The fuel filter is part # 35.
