Chris, recheck battery connections too. A boost and it goes may indicate a poor connection or a faulty battery.

thanks, took them loose and ran a post cleaner on them, tightened back down, all good, nothing changed

Double check your battery ground as well. They are usually just bolted to the frame.

yep, first thing i checked actually. Learned that on the polara.
