I'm back - Stalls at over 3900 rpms - alarm & high temp light. I turn key off, wait 30 seconds & it restarts & goes no problem, but exceed 3900 rpm & stalls. I've replaced all fuel filters & racor (all ok except hp which was dirty & collapsed) drained VST 3 times & fuel clean ea time. Tried to get codes but just solid red light. Finally took to local Honda mech & he checked & found constricted fuel line at grommet through the cowl & replaced the line. He also replaced water pump & thermostats thinking it could be temp sensor putting engine into safety mode. Some other clues- fuel bulb stays semi firm. I tried pumping bulb while running & still stalls. When it quits it sometimes just quits entirely or rough idles. I run off 3 tanks & it happens on all tanks. Honda mech thinks maybe faulty temp sensor - high temp light & alarm should not go off if fuel problem. Any help/ideas are appreciated - Thanks
