Might be ur Fuel pump ! , I would spray a mist of gas in the TB if it revs up ,I would be looking at the pump, You then could do a fuel pump pressure reading. Has the bike been parked for a time ?

remove the airbox cover...then remove the airbox inner lid which exposes the throttle body just like joe mentioned. get yourself a small bottle and put a few ounces of gasoline in it. try to start the motor. if it won't start dribble some fuel down the throttle body then see if it starts. if it does but stumbles try giving it a small amount of throttle and dribble some more fuel into it. if that brings it back to life you have a failing fuel pump. i stock both new complete OEM pumps as well as complete pump rebuild kits. contact me if you need help.

Thank you! Been off line. This is my first Buell. Is the fuel pump hard to get to / replace? Have only replaced the plugs and TPS so far. If I let the bike go cold, do TPS reset. It starts right up but only runs a few seconds. After that I have to really work the throttle just to get it to start. Will not idle on its own. Will the Buelltooth give code for fuel pump? So far, no code.

Welcome to the group , show some bike pics please.
If it was parked for a while with old gas in it, could be the pumps tea bag filter clogged up .

Not at all. Can be a 15 min job.
Hang the rear of the bike slightly off the ground with an A-frame ladder using a ratchet strap over the ladder and to the pillion peg mounts.
remove the lower shock bolt and let the swingarm hang.
Use masking tape to protect the swingarm paint
use tin foil to shape a funnel from the tank drain plug (left rear bottom 1/8" pipe plug)
Use a big enough drain pan! Open the gas tank cap to speed flow.
Remove the electrical plug and the 4 perimeter bolts.
A puller helps (PM Chickenstripen) but you can carefully get a sharp flat head in the gap to release the whole end cap.
The fuel pump is mounted to the cap and you can see the condition of the tank (corroded?), sock (plugged?), low level float (sunk? missing?), and wiring (chaffed?).
Lunaticfringe offers pump re-build kits or whole new pumps (Test it first)
The pair of o-rings may be a little swollen to replace the assembly immediately, but if they are in good shape leave them out to dry and they will shrink back to be able to install them with a little o-ring lube, oil, or vaseline.

here's the link to see a complete kit. a factory NOS new-in-box pump is about $100 more. pump assemblies can be a bit challenging for a novice to correctly rebuild so you might just want to go with new. contact me and i'll get you fixed up.
regards, john

Yes. I tested 3 times. About 8 drops if gas down the throttle body. Idles nicely at about 1200 for 10 seconds then seems to run out of gas. Same thing every time she takes a little fuel from a cup. If I add a little gas while she's running, she still dies. Regarding the fuel pump unit.. Looks like I have to take the rear wheel off too? Because the tire will hit the stock muffler preventing the swing arm from going down fast enough. Right?

No , not necessary, Just back out the axle to take the pressure off the belt and it will lower enough.
