could be a couple of things, first look to the gas tank vent, how much gas is in the tank, the lower the volume the longer it will run before the vacuum gets high enough to kill the pump and the second would be the pump its self is going bad. loosen the tank cap when it is running bad, and see if it will straighten up if it does you have a bad tank vent if it doesn't, then look at the fuel pressure and see if the pump is getting hot and not getting the volume of fuel to the engine.

Thanks for the info Dave .... Got to let it sit now as it won't start now.. soon as I'm able to
Check it out I will power my findings......

If it starts and runs cold and has no power when warm. I'd say it needs a new catalytic converter. Sounds like it's plugged.

Ok so I open the gas cap and nothin changed I pushed the valve
On the fuel rail and ????? Air then gas and if I only push it in a little
Get a lot of air then fuel????

[frank]

It don't have a cat on it when I got this it run great cold or warm and. Now runs like crap if I let it sit for a day or too it will fire up and run fine when cold (hour or so) then its as if it starts running out of fuel
When it starts acting up if you give any throttle it will spit and sputter then die and won't start back up
For a fire hours or day..........

[frank]

Few hours not fire
