Help with vmax twin issue

[JacobM03]

Im having an issue with my 1998 vmax 600 xtc twin. I went for a ride today and was cruising around 6000 rpm down a narrow trail giving it frequent throttle blips when my sled suddenly died like if I were to hit the kill switch. I couldn’t get it started back up after and that was after 30 minutes of riding. Took the belt off and Brought the sled back to my yard, a few hours later I switched plugs and it started 3rd pull and ran abit roigh for a minute and then ran fine, I shut it off and put belt back on, went to start it an hour later and could not get it going. I boosted my battery and cranked for awhile until it started, let it warm up and drove it around the block, as soon as I pulled in the yard and let go of throttle it immediately died and would not start back up. Checked spark and its there and blue, waited a few hours and started it first pull full choke, it ran for about 15 seconds and died again instantly like if id hit the killswitch and then wouldnt start.

What could be causing these issues? I check white/red and white/green coming out the stator and got 207 ohm, check brown and black/red and got 250 ohm (this was all cold at -10°c). Seems like its getting decent spark and these issues just appeared after running fine for all season.

Im not sure what this could be im thinking possibly cdi if theres a way to verify that or check other things, thank you for the help in advance!

Plugs were not too bad, not really a difference with new plugs in.

Check all the lines and seem fine, pump works good too.

And I haven’t looked at the fuel filter yet.

It sounds electrical. Are the kill and keyswitch in good condition?
Is the spark plug coil mounted on the airbox oem or aftermarket?
Is the orange wire for that coil plugged in properly?
What about the ground wire where the screw holds it onto the coil? No rust? Screw tight?

Kill switch and keyswitch work, bypassed them and same issues.
Oem coil on airbox, tight screws and ground is clean. Tried it with the coil off my phazer and same issues.

I changed to fresh plugs again yesterday, it ran for maybe 15 minutes and full rpm no stutter, let it sit and idle after and 1-2 minutes later it died. Would start first crank run a few seconds and die again and then after that wouldn’t start.

Tried it again today, started 3rd pull full choke, ran a couple seconds and then died and wouldnt start again.

Checked the fuel pump pulse line and it was in good condition, will put a new line just to be safe anyways.

I just took off gas tank and checked the filter, looks pretty dirty, can blow through it easily but I will take it off and just run an inline filter for now and try that later.
