Xj trans cutting out and in

In neutral heep rrevs up great
Runs great

Sometimes drives perfect ,

Will cut out on throttle and almost stall out

Was doing this once a day. (over 100 mile days ) then stop after a few seconds

Now is doing it and continues to do it.

It makes a dull popping noise when I try to throttle , can tell if its exhaust or transmission.

CEL came on but its an o2 code I believe from it trying to stallout.

Help me out here its my current daily driver and its my form of income.

Also putting it in 1-2 or 3 doesn't change anything ,

Will do it in reverse as well

Drove it for an hour this morning cant seem to get it to do it for longer then a few seconds now

 

[transman731]

when it starts to do it, can you throw it in neutral and it acts normal?
it sounds like the converter is bad but hard to say from just your explanation.

 

[CThurmond]

Yeah when.its doing it I can.pop it into N and it revs up fine

 

[89wrangler]

Sounds like torque converter.

Sounds to me like the fuel pump....my 96 did the same thing....got a CEL for running lean and rich....neutral would rev fine, but once I drove it for a while it would cut in and out and sound like it was backfiring.

Put a torque convertor in it and drove it 120 miles seems better
