Hello. First post on this forum. Glad to have found it. I'm working on a Yale GLC050TGNUAE088, serial number E187V20019A with a Mazda F2 engine. Engine was running fine but was overheating due to leaking radiator and head gasket. I replaced the rad and the head gasket. The head was rebuilt when it was off, timing belt was replaced as well as spark plugs. Engine started right up after repairs and ran fine for 1/2 hour then quit. There wasn't any bogging or rough running, it just shut off. Engine turns over fine and ignition system is producing good spark. There doesn't seem to be any propane getting to the engine. It will kick on starting fluid. Swapped on a full propane tank just to be sure with out success. The evaporator is an electronic version with what looks like 2 electric lock valves. Any help would be appreciated.
