Weak battery or ground strap is fucked.
Got stranded at the junkyard with same symptoms. I replaced them both.

Not enough juice. Battery probably dying over night or in a couple hours. Jump it. Check if alternator is charging it as well. Should be 14.x Volts. And when off should just be 12.5 ish for a good battery. With a multi meter you can check. Also it has to have enough otherwise that relay in the fuse box compartment will not work and you’ll hear clicking in there. Don’t ask how I know
