Dual fuel (petrol/LPG) cars that are run soley on LPG for extended periods often end up having problems with the petrol fuel system.
You said you had to drive idling on 4 low to get TO the petrol station, how was it after you filled with fuel? Or did you just switch back to LPG?
Your fault could be anything from stale petrol, faulty fuel pump (as you suggested), blocked fuel filter, blocked injectors, or even something like faulty mass air flow sensor.
I would be diagnosing further before you start spending money replacing parts.

I would agree with YNOT. I run dual fuel but I make sure a put a tank of petrol though at least once a month - my preference. I have been through a similar process where I had to eventually diagnose a dodge fuel pump. I was getting fuel starve over 2200 rev's. Wasn't running rough, just dying.

If it is coughing and spluttering, then maybe more towards stale / dodgy fuel. Cheapest way to start is empty fuel tank and fill with fresh good fuel. Replace fuel filter, and maybe mix in a bottle of injector cleaner and drive off and on for a week between petrol and gas. You can also get a mechanic to pressure test your fuel pump to see what it is putting out.

See if there is any improvement. After that, you can look at getting your injectors cleaned and the spray patten tested - but $$$ more expensive.

Hope it helps
