Couple of quick questions, Bill.
What year model LT?
After it dies at the stop, does it start right back up and then die at the next stop?? Or does it play hard to start? And does it run fine as long as you're not stopped?
it starts but idles slow and a little rough
Did you have the battery dis-connected for any reason? If so, maybe try the *key on; twist the throttle to wide open and return - twice*. Then, start the engine and ride around the block. This resets the TPS (throttle position sensor).
Yes I service the battery , water level and charged
If you changed the fuel filter, then you removed the gas tank and like Raffy suggested, check for those lines that run near the tank. Gonna be removing tupperware again, butt first - open the gas cap and listen for any 'whooshing' sound. If none, then I'd retrace my fuel filter install, hoping that you didn't just fill the tank full!!
(Question to myself - what happens if the fuel filter direction of flow arrow is backasswards??).
The fuel lines under the tank were set up male female and female male.
Hope it's an easy fix, Bill. The big boyz'll be on here in a bit and gitcha rollin', I'm sure. Good luck.
