Same problem on my Sub 91 Liberty. Changed the ignition coils and it went great guns for about 3 months but problem has come back, however the stalling isn't nearly as bad as before. Earlier I changed the alternator+battery, spark plugs and leads. This had no affect on the stalling.My fear of hills is returning.

Have the battery and alt tested for free at the local parts store. Tell them what it's doing, and start suspecting a fuel issue. Could be getting the right amount of fuel but not burning it. (plugs, wires, coil) Or could not be getting enough fuel.
Still hard to say, so get the charging/power system checked first. Let me know what you find out as I'm real curious now.
Same happened to a friend and it was the fuel pump.... Same for another friend and it was 2 bad coil packs.
It's known as "pinking" and can be caused by a few things. 1, fuel grade/mixture. 2, spark plug gap/grade/dirt/leads breaking down. 3, timing out slightly 4, rotor cap damp/ old Check them one at a time until the problem is solved.
There are a few things that cause this problem, by far the most common is the check valve in the fuel pump is not working, this lets the fuel drains back to the tanks and causes long cranking times and stalls cold (sound familiar?) the next less common is carbon on the back of the intake valves, and the last is not using the correct grade of fuel, example if your car requires 87 octane don't use 89 or 91 octane it causes cold start problems.
You are boiling the brake fluid and hence the sinking pedal, go to silicone based synthetic fluid, it will not boil, all the old fluid must be flushed from the system before installing this fluid, this should cure your problem for good.
