Default looking for opinions/ Help advice..

Saturday night I put gas in my Blazer drove it 5 minutes and parked ..After 20 minutes I started it up and attempted to go home. I started up a small hill. I got halfway up and the truck started sputtering and acting as if it were out of gas. It then shut down. Had to back it down the hill and parked it. I tried starting it numerous times and it would start up but then in seconds started sputtering and shutting down again. Someone told me it may be bad gas. So I put a bottle of HEET into the tank and after several attempts the truck would start and continue in idle mode for up to a minute before shutting down still.. After 2 hours I had it towed home. Then on Sunday I was able to get it started and to idle..I left it idling for 2 hours then tried to give it gas. The first few attempts to give it gas it sputtered then almost shut down. I was able to get it to take gas without sputtering. As soon as I put it in drive and slowly rolled forward it sputtered bad and was about to shut down. I put it in reverse as soon as I gave it gas it shut down..
Does anyone have an idea on what this may be. Is this actually bad gas possibly or is this fuel pump or fuel filter related. Not in a situation at the moment I can have it towed to a shop and pay a ton to have it fixed so kinda have to see if I can get it figured out and do a D.I.Y on it.
Any info and knowledge I cvan get on it I figured I would get the best here on the forum..I appreciate any help/Info anyone can give me in hopes to getting my truck fixed ..Sucks not having a vehicle..
Thanks so much guys.

You could probably borrow a fuel pressure tester from an auto parts store to determine if the fuel pump is bad or not. There several threads on how this is done and the pressure the pump and system should sustain.

The link in my signature block will take you to the thread Christine is referring to. Follow Captain Hook's directions. In the meantime, disconnect the MAF sensor and see if that makes a difference. Another possibility is a clogged cat/exhaust. Run through the fuel pressure test and let us know the results.

Finally got a scanner on there..Got a nice bit of codes to try to look into ..
po128
po154
po155
po300
po452

Just a quick question as I cant seem to find out the info online..The 02 sensors have a little plastic tab lock like thing holding them in place..Is there a trick to getting that out. Have tried screwdrivers to pry push and no luck as well as other things..Cant seem to get those tabs out of the clip..
As always appreciate any help..

The OBD-II Codes read
P0128 etc.

Try with a 0 (zero)

P-zero-one-two-eight

Thanks man much appreciated..
I finally got a fuel pressure tester hooked up and my blazer was not even getting 10 psi at the fuel rail.
So I have a new fuel pump on its way from partsgeek.com
once I get that installed then I am going to run the scan again and see what I get at that point.

One thing that I was always told was that if you're replacing the fuel pump that its best to go ahead and put in a new fuel filter also. Cant remember the exact reason right this minute but it made sense to me at the time and I have always done so. Some new fuel pumps may require a fuel filter replacement as part of the warranty.
