Hopefully there's someone on here who can help with this - my LPG experience with Pandas is very limited.
From experience with Land Rovers, this type of problem may well be an LPG-related one, as the LPG kit tries to fool the ECU into believing that it is still running on Petrol by spoofing the readings from various sensors. Have you contacted the LPG installer? It could be a known issue, and an easy fix.
Apologies for not being able to help more, & good luck with fixing it.
