Needing help With a 1991 GTP stalling out on me.

I have a 1991 Grand Prix GTP 3.4, every thing was running great while I was on the highway when I started to loose power then finally Died on me. It would crank when I turn the key would not turn over.
 


From the information there is i would guess possibly the fuel pump died or maybe it ran outta gas.

When you say loosing power do you mean it sputtered and chugged or did it just start slowing down so you had to keep giving it more and more gas like when you go up a really steep hill

If it's a 5 speed and you end up not fixing the car i'll buy your tranny.
 
Sputtered then went down hill from there, and when I pushed on the gas I did hardly anything. Still had all electrical power.
 
sounds like its not getting gas, or the cat clogged up real fast.

beat on the bottom of the gas tank, see if it fires up after that. if it does, the fuel pump is bad.
 
Ok so update if anyone is looking. I have checked spark and fuel it's getting all and I got it running but if I rev it high it seems like it want's to bog out like to much fuel, so how can a fuel injected engine be flooded out?
 


And just so you all know just in case yes it's a "X, vin 3400" I feel dumb outtin it up but I just like to be as thorough as I can.
 
if it will idle. spray some carb cleaner at the vac lines.

is the check engine light on? if it is get it scanned at a parts store, its free. it will tell you whats wrong.
