2005 1500 suburban started to sputter when pressed on gas or let off gas it would die, we started it back up went about 1,000 ft and the same thing happened. we managed to get to a church parking lot with it doing the sputter and die on us four diff times, finallly after getting parked in the parking lot it just wont start.
we changed sencers, fuel pump, everything we can think off. checked fuses ect, it gets fuel, compression, and spark, but wont start, it acts like it wants to start, after changing fuel pump it started for like two mins and then died,
we have spent over $1,000 in to this and need to get home,

Hello, you changed so many parts and spent so much money -- but what testing has been performed? If you have fuel delivery to the engine, why waste the money and effort to replace a fuel pump? If you can't confirm that's a problem, your guess could cause more and new problems.
You need fuel delivery (which you say you have), ignition spark (which you say you have), engine compression (which you say you have) -- but also needs to ensure the engine in proper time, need to verify you have the proper amount of air getting into the intake manifold -- not too much, not too little. You also have to ensure both intake and exhaust systems are free of restrictions and that the emissions system is working properly.
I appreciate the efforts, but often wonder if you'd have spent less and have fixed it sooner by having the vehicle professionally tested before guessing at part replacement.
