I have a Saito 82 that I've had for several years. The last few flights my engine stalls in mid-flight at or around 6 minutes into a 13 minute flight. I've tried new glow plug...new fuel...reset and reset engine settings. I get perfect performance at each full tank but again...at 6 minutes engine sputters...and stalls. Tired and freaked about the number of deadsticks I've had to deal with.

Please help!!!
