How are your battery connections...check for terminal corrosion and tightness of lugs....check the grounds to be sure they are tight.
That was going to be my suggestion. Those battery grounds, exist in bad joo-joo environment. When we purchased our coach and got it home, we didn't have any ignition or, starting problems but, in doing a thorough inspection of the entire battery system, I crawled under the big beast and found the ground cable attachment points on the frame. Wow, those were seriously rusted/corroded. I was amazed that the big CAT even cranked over with those looking like they did.
So, a bit of up-side-down work for a while and I had clean, nice connections. So, it maybe worth a look-see at those ground connections. They're under the phrase, "Out of sight/Out of mind" thing.
