Lately driving my EL when it was still cold (both the engine and the ambient temp) it randomly stalls when accelerating. It did it once in the middle of a roundabout, and again in the middle of a set of traffic lights. I think my EL is trying to kill me.
Also a couple of times ive noticed the gauge reading just above empty, when it had quite a bit more than that. Doesnt do it all the time, usually when its fairly cold.

Obviously this is on LPG and only on LPG.

Is this the cold weather related? Being a gas are things freezing up or getting real cold?

yes, freezing up-what tep. do you run,you mayhave to run a little hotter and bleed the converter,make sure it is lower than radiator over flow and hoses are big 3\8 - 1\2 inch bore and good flow,the hoses should be hot in 1-2 minutes or it will freeze the coverter,no leaks in system -----mines just cracked a elbow on the heater valve block and freezes some times if the water level falls too low. hope you use anti freeze-rust inhibiter,it works well

Definately sound like convertor icing up check your coolant level.
