Make sure that the timing is correct and that the spark from the coil is healthy. Problem can also be with the overdrive in the converter. If it's stuck on it can do that too.

SOURCE: 2002 jeep grand cherokee with 4.0 engine will die but restart

p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.

When i start my jeep in the cold mornings it starts up but bogs right down and stalls then i have to accelerate for the second start up for a few minutes to warm it up a little and then it bogs and stays...

Your only problem friend, is the temperature sending unit/sensor. Upon cold start, this sensor wil tell the computer to go into cold start mode putting a bit more fuel in and raising the idle a bit to keep it running when cold without using the throttle. Replace that sensor and your good to go. Makes sense, right?

My 5.2 Grand Cher. will not accelerate above 2k rpm and will lose speed on hills. Even with foot down to floor at 15mph it has slight surge and starts to bog

the most common problem is the air mass metor this controls the air intake which sends a message to your ecu if it sends the wrong message your car will go into limp mode

2000gc wont accelerate... Fuel filter??

Change the filter first and see if that helps, if not, have a fuel pressure test done.
Also check all the vacuum lines for bad hoses, all it takes is a pin hole in these damn emissions systems to screw up the whole system.
