You might have another faulty CPS.
Check fuel pressure on the front rail that connects the injectors at the Schrader valve. Should be >3.8 bar when cranking. When last did the car have a fuel filter?
If CPS & TPS are OK then it is most likely fuel starvation due to a clogged filter or buggered pump.
Please read stored codes on the car with an OBDII scanner & post them.

Battery /altermator.... Means your alternator is not charging... Pretty straightforward problem, the way the charging system is designed, the BATT warning will come on if the alternator is not sending power!
Did they not notice that BATT/ALT light??

I also faced the same problem. I have changed the catalytic converter from http://www.cwik.com. I am so pleased with them as they offer very cheap price and free shipping.

hi there sorry after all im a woman dont know what CPS &TPS are got a qoute back from them today of R30732.65 for a catalytic replacement..........but still why do my car die and I get a malfunction of battery alternator visit workshop my mind tells me if that is the problem why can my car start and everything else clearly if it was the cat why didnt they pick it up 5 days ago with the s diagostic why onlu now if its such a big problem making my car die
CPS = Crankshaft position sensor.
TPS = Throttle postion sensor i.e the throttle pedal.
Please ask them what codes the car is displaying & post them here.
Your Cats will not stop the car from running unless they are totally clogged & they are obviously not otherwise you would not have got part of the way back to Cape Town
You need to have them look at the charging circuit. Something is wrong but it must be charging or you would have a flat battery & not be able to crank the car over.
You MUST check the fuel pressure. A borderline fuel pump or partially clogged fuel filter can cause what you are seeing.
Don't pay anybody for new Cats until you post the codes the car is storing. Make sure you use a reputable dealer or someone competent in Cape Town like Stanley Wilkinson or Russell Ormarod at Car Electric in Montague Gardens.
Good luck
