4.3gxi bad temp sensor?

Could it be a fuel issue? If I have the bad motor running and start the good one, it’ll cause the bad one to cut off.

Anything is possible but both idling shouldn't cause one to die. If electrical connections are bad, maybe

Alternator outputs the same when running, should be around 14V+

When the bad motor was running and I had given it throttle to stay running and I turn the other motor on, the bad engine would shut down like it was cut off from fuel.

Sure sounds like an electrical problem

Now I tried starting it this morning and it won’t turn over. I hear a click when I turn the ignition, removed the starter motor and solenoid and that worked when I tested it. I put a brand new battery on that engine a few days ago and it’s been on shore power this entire time.

Look real, I mean really, really close at your battery cables.

Try to bend the cab;e ends enough to see under the insulation jacket on both Pos and Neg ends. Wouldn't be the first time that a cable looks great but under the jacket it's corroded
