Runs sluggish for 5 min then stalls,wont start again for hours

Question edited for clarity.
Question moved to model category.

I am in two minds whether you have two issues or just one/

Bike runs and stall out, could be a few things, like a fuel hose air lock, I have seen that a few times. Or it just ran out of electrical power because the battery went flat (total loss system) I had that on a Kawasaki H1 500 triple that I took to the Isle of Man TT. I rode it home with a car battery on the back rack. That was caused by a faulty rectifier.

My guess is that you have a broken wire in the harness somewhere. Is the battery connected to the right polarity. That is an easy mistake to make. Tip, get the wife's red nail polish and put a line around the positive terminal edge and paint the hard to see black, raised plus + sign.

See if you have an Motorcycle Electrician near you. You need someone with access to the wiring diagrams, the ability to read them and the test equipment. This link will find someone close to you.

I wonder what the fuel problem was. It kind of sounds like the idle jet, and/or low speed jet needs to be cleaned. Also while your in there, i would clean all the jets, and check the float bowl height.

Great bike I use to have a 81 XJ650J, hell of a bike, i miss it.

check the kill switch, all the fuses and the key position.The ignition switch may need electrical contact cleaner.

2 things need to be done first start your bike get a can of wd40 after your bike is warm and running spray around the carb jointsall 4 of them if your engine changes rpms up or down you have a intake leak ether your carb joint gaskets or o-rings need replacing or your carb joints are old and need replacing. at this point wont hurt to have you carbs cleaned also

The plug is getting fouled out cause the carb is needing cleaned. It will need to be removed and disasembled to be cleaned.

the battery is failin or not charging rite-on a coil ignition u always need 12 V cause the bike doesnt feed off alternator like a car--test it -may still be good but charge it before cruzing

sounds like what happens to my bike when i forget to put the fuel knob to on. could it be a clogged fuel filter or line maybe.....?

Pull the float bowl caps off the carbs and then spray carb cleaner into the main jet and all other accessible ports on the carbs. Chances are there is a build up of water condensation in the carbs.

Check the intake manifold/s, even a small leak will make it run poor. Being stored for five years then putting it into use, you may have a blocked main jet. Sea-foam is a great product and I would have used that product to store the bike but not to get it running. It is slow acting so it doesnt work like carb cleaner.

seems like an air-locked gas tank (remove gas cap as a test) or dirty fuel filter....
