I was reading the posts you guys put and it was as if someone else was
describing my vehicle. I started with a check engine ligth when the
gauge approached empty. Then came the blinking fuel light with the
check engine, and now I fill up and get about 200miles before my gauge
shows empty. Has anyone pinpointed down the part and repair since
these posts? I want to do the work myself to save the labor costs and
I have access to a lift, but was wondering if anyone had actually
bought the parts, attempted the repairs, and the results. any help
would be greatly appreciated.

Yep, that's apparently a known issue, and of course, not under warranty
unless the whole fuel pump goes bad.

What you need to get done is change out the "Fuel Sending Unit". Its in the
gas tank near the float. I got it done at the dealer for $260. Not cheap,
but I had not other option. It seems like you do, so let me help you out
even further:
