I am sorry for the long wait

so when this acts up you physically push down in those fuses and the vehicle will start up right after you do that and run fine for a while ?

Customer: replied 2 years ago.
you can also wiggle the wiring harness's that go to it same result . fuses and relays were super loose first time
Expert:  Gary replied 2 years ago.

is there anyway you can narrow down the wiggling to a certain fuse or connector into the box ?

Customer: replied 2 years ago.
no and the problem is getting worse
about to take the top part of the fuse box apart to see if the problem is there

at this point the odds are box itself internally is bad but before you replace the box what you can do is get something small and sharp like a dentist pick or something like that and one female terminal at a time tweak over the centers of the female terminals one at a time until the centers are just about closed off so you know every terminal will be making a good connection when plugged back in

if it still does this you will need to replace the box if the problem goes away you fixed a few bad terminal connections and it should be fine and not act up again
