i have a 1999 Suburban w/ 138000. the last 2 weeks it has started to bog down as it is shifting as if the fuel filter is plugged. i changed th fuel filter a few days ago and the fuel pump was changed a year ago. i thought maybe some bad gas, si i have ran premium gas to burn out the old and it continues.

How long since a tune-up? Any applicable trouble codes? At the least, you would need an obd2 code reader. Use a gage and check fuel pressure. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't one. If you have the spider fuel system, sometimes the fuel poppets need cleaning.
