Peugeot 206 issues

I have a X reg 1.4 lx 5 Door. I’ve had it nearly 3 years and all was
fine until about 6 months ago. I was driving to the airport nearly
there and my battery light started to flash on and off, didn’t appear
to be any reason for it. It then about 5 minutes later started
pulling back and just didn’t want to drive. There doesn’t seem to be
a reason why it starts to do this and it is awful to drive. At the
point that I’m scared to drive it. I’ve taken it to the garage but
they can’t find a fault. It’s now happening everyday and I’m quite
worried. It also every now and then just stalls when I’m driving
along. Any ideas how to fix any of this?

Thanks

 

I`m am not too well up on Peugeot electrics but it sounds as though it
may be a bad earth - either to the engine or gearbox - i have had this
fault a few times with Fords and once on a Vauxhall where the earth
had completely broken off from the gear box !
Check all earth leads from battery and also from chassis/inner wings
to gearbox or engine - hope this helps !
