JLG 450A boom lift ran fine in December 2014 but not used until April. Started fine on gas but then quit 10 min later and would not restart. I put a tank of propane on and it started and ran fine but the engine malfunction indicator light stays on. I caned the fuel filter and I got it to start for a few minutes but it will not start on gas again. Any Ideas? When running on propane the engine malfunction indicator light stays on.
