Doosan (& Daewoo) G25E-3:
Rough running after warm up, restart runs fine for a minute then rough again

Hi, We have a Daewoo lift truck with g25-e3 propane engine. After about 10 minutes of running it begins losing power and running rough. Sounds like it drops a cylinder. If I turn it off then restart the engine immediately, it runs fine for a minute or two then back to rough. I can repeat the cycle over and over. Plugs, wires cap and rotor have been replaced but the problem persists. HELP!!
