Yesterday was on the lake and hauling butt when the motor started backing down. Thought maybe one of the points came loose as the motor seemed to run at maybe 30%. Got home and checked but all was good there. Today put motor in pastic barrell and it seems ok but no load on motor. Could it be bad fuel mixture? I have a 3 gallon tank witch was maybe 3quaters empty when problem started. Any help out there?

Good chance you not getting spark to one cylinder. When it is performing badly you can do a spark gap test or simply remove on plug wire at a time to see if it quits when you remove one or the other. If it quits the one you just removed is the one that is working right. Best of luck. Rick.
