PD 37efi - stock - 15 hours. Ran for a while scouting today and the motor would randomly bog down for a fraction of a second then go back to full power. It never completely died. Could have been a coincidence, but it seemed to happen more frequently in rougher water on the main lake. It would sometimes go fine for 15 minutes then do it once, and other times happen a few times a minute. There was about a gallon leftover gas that is less than a month old (with stabilizer in it) and added 5 more gallons this morning.

Planning to dump the tank in the morning before I scout another lake. My top suspect is bad gas, but wanted to check if it sounded like anything else.

if it actually did get worse when in rough water, you probably have a bad connection somewhere.

You guys nailed it. Loose negative battery cable. Thanks fellas
