Have you checked fuel pressure. Sounds like a clogged fuel filter & or a bad fuel pump,that once in awhile binds up mechanically,them is okey for awhile. The time you have to wait,to start it,is just a coincidence.
I would do voltage drops on both battery cables,or just put on new ones. Don't cut off just the ends,replace with OEM Type Cables,end to end
Also,the contacts,inside your starter solenoid,may be burnt. If it won't turn over ,and just clicks,pull the starter and just replace the solenoid,not the whole starter.
Also ,there should be a fuel pump relay. It's coil or contacts, maybe your problem.
Do not clean the ground cable,replace it,and have your dad check the inertia switch,add grounds to the battery to the frame,and the body to engine,see if this will help.
