I bought a new battery for my '03 883. I cleared ALL the codes (but still have a ??? about this). It started up yesterday evening. This morning however, is a different story. It started, went to get fuel, it wouldn't start back. Husband came & got me, loaded the bike up in the truck. Got home, it starts. I've noticed the pattern of it turning itself off when it gets hot, & not starting till it cools off. Everything else seems to be fine. Now the codes. 1-7 cleared. 8 said SEE but cleared, 9 &10 clear, then it says PPU and 78637. What is this and why is it running till hot, shutting off, then starting when cooled? THANK YOU TO ANYONE WHO CAN HELP!!!!! I NEED IT!!! I replaced the o-rings myself. I've done all the work myself. I just can't figure this one out.
