When I fish, it is trolling with the 9.9. When we decide to move I fire up the 200hp and off we go on plane 5000 rpm. About 20-30 seconds later the 200 suddenly stalls like no fuel. It will idle OK. After 30 more seconds of trying to get it going to plane (bucking and stalling) it finely runs fine all the way to max rpm like nothing happened. It only happens when the 200 has cooled down or not started for a little while (maybe 1 hour or 2). I have scoured the forum looking for a similar post. Is this a temperature (t-stat or sensor) problem? Or fuel delivery? It doesn't happen if I let it warm up by idle first before I put the hammer down. 500 hrs on motor, racor OK. Any ideas?
