I have a 2005 90hp johnson 2 stoke with auto oiler. In loading the boat on trailer last weekend I got crossed and had to reverse hard a couple of times rapidly. The last reverse the engine died and would not crank back up. It still want fire. What did I do wrong. Fuel seems to be flowing. Pulled filter and it is not plugged.?????? Why would it stop firing all at once. Ran great all weekend. Engine has maybe 80 hours on it.
