Stalling 95 ZJ when brakes are applied.

I have a 95 4.0 Laredo. The problem started while climbing a logging road. Slowing to go through washout ditches it stalled a couple of times. We then had to climb over an inclined snow covered section. Took 5 good runs to get up the hill and the Jeep was trying to buck and stall but it did keep going. I thought it was a fuel filter problem. Made it through and when returning down the hill stalling problem continued through the ditches. Highway return was without any problems. Next day problem was back and happens often. It's not safe to drive at this point.

Symptoms- Traveling at say 30 mph and apply the brakes hard the motor will stall at say 10 mph before coming to a complete stop. The motor cuts out rather than stumbling to a halt.
- Slowing to say 3-5 mph and making a right angle turn and motor will stall basically at the apex of the turn.
- Engine Vacuum 15lbs at idle and cruising speed. Seems low to me.
- Idle seems a but rough but it has been this way for years.

I have since replaced fuel filter, TPS (needed one for a while) and checked and cleaned all sensor connections and applied dialectic grease to them all. Put in injector cleaner but I have only driven it say 30 miles since putting it in.
Any input would be appreciated.
Thanks

How many miles and what transmission?

First thing I would replace is plugs, cap and rotor. If it has been running rough for years and those items haven't been replaced in the last 30k miles, then colder weather could cause rough running to turn into no running.

Thanks for your reply to my posting.
All of those components are fine and stalling started in July.
I wonder what the vacuum should be?

Auto with overdrive and 175km

Not sure about the vacuum, but an inspection of the vacuum lines under the hood would be a good idea.

How is the air filter?

Some older Jeeps have an issue with fuel pressure, so you may want to have that checked also.

Air filter is good. I will check the fuel pressure and see if it's OK
Thanks
