2002 Durango won't crank

I have a 2002 Dodge Durango 4.7 that
won't crank, particularly when it's hot. All
power turns on, but it won't actually start
for about an hour. It seems to happen more
when it's hot out, but I can't find any
correlating factors with it. Runs fine &
always starts up eventually, just takes
awhile. I also have other odd electrical
issues such as the speedometer/odometer
not working, ABS light on, back some light
not turning off (I had to remove it), etc.
could this be an issue with the fuse box
under the hood or certain fuses? I'm not
extremely mechanically inclined could it's
possible I'm missing something big.
