My 2007 50 hp. e-tec misses (like shuts off then back on) only for a split second. Some of the time i can run it all day and it won't do it. Some days it misses off and on all day. I get gas from different places . Tried different tanks. Had it in the shop 5 times they run it under a load and it won't do it in the shop. Other people i know with other e-tec's {bigger and smaller} are doing the same thing. Any help would be appreciated.
