'97 Jeep Wrangler Fuel Delivery Problem

Evening Gents 
My jeep died twice today taking off from a red light. When I took off it sputtered and died almost like running out of gas. Started pretty quick but had to pump,the accelerator a bit. Does this sound like a potential fuel pump issue or maybe needs a good fuel system cleaning?

Check the throttle body. I forget what models/years had issues but a buddy at work had to replace one in his several years ago.

Sounds like a pump to me

What is the mileage on the engine?
Has the fuel pump ever been changed?
Are you the original owner?
Is your check engine light coming on?
This information will help. Generally, Jeep electric fuel pumps go out around 150K miles or so, that is my experience anyway.

How accurate does your fuel gauge measure your fuel?
I'm asking because the first sign I had that my XJ fuel pump was heading south was inaccurate fuel readings.
The fuel pumps in Wranglers and XJ's are a combination pump, filter and sending unit.
One day I was driving to Lafayette and got around Carencro on I-49, fuel reading was 1/4 tank. All of a sudden it just started sputtering and dying. If you are getting inaccurate readings, I'd bet on the fuel pump.
The next day was a Saturday IIRC, got a fuel pump and installed it, was about a 5-6 hour job.
No problems after that.

There should be a strainer on the fuel inlet at the intake. Remove line and make sure its not stopped up with debris.
Usually signs of a bad pump or clogged strainer is missing under full acceleration when fuel demand is highest.
It's an electric pump located inside the fuel tank. New one is like $90. It's not too hard to replace really compared to some.
Siphon fuel out as much as possible.
Place floor jack under tank.
Losing straps holding tank with a buddy keeping tank balanced on jack.
Slowly lowers until you can remove fuel line at top of tank.
Lower tank and empty
Carefully remove pump
Replace pump and gasket (if inatalled, can't remember)
Reinstall.
Be dang sure you do not create a spark when doing this stuff. You will regret it if you do......or your family will actually.
