My 87 trx350d just died today while riding. We pushed it off and it seemed like it was dying and just had no power. Then we jumped it with the truck and it ran great for a couple of minutes then did the same thing. When its connected to the jumper cables it sounds and revs perfect and runs strong for a few minutes.

I’ve heard that these don’t run good even if you jump then when the battery is shot. Any truth to that?
