LP gas, 4 cyl, late model cat lift, one ton. Ran fine, changed oil, oil filter, air filter. About 3 days later the unit just loses power if the pedal is pushed beyond 50%. I know the oil change had nothing to do with it, but that's all I did. Idle is fine, starting is fine-seems like it's starving for fuel-changed tank- no difference.
Thanks for any help
