I have a 2006 f150, I will start from the beginning, I lost all electronics one day radio, heater, lights but truck was still running, drove back to my driveway, truck shut down try to start it and it wouldn't, try to boost it and it still didn't start, so I left it over night and in the morning went out to see if it would start and it did, the following Monday took it to work and when I get to work it dies again, clean all connections, checked the battery, starter and alternator, the alternator was no good, replaced it and the truck still won't start and everything is where it should be alt, battery and starter, all the electronics work, any thoughts I what I can do next.

Thanks

Losing all power is a sign that you have either battery or alternator problems. How are you sure the battery and alternator are good? Do you hear the start solenoid 'click' when it's dead, or do you get nothing at all?

Not start does that mean no crank or is it cranking .
If its not cranking is starter solenoid getting start signal ,I know its under the truck but you have to find out .
If its cranking do you have the feeling that its no fuel? Look at FPDM above spare tire ,if its corroded or not on standoffs replace it . If it isn't bad it will be .
Look for corroded wires lose connections . Including grounds .
This is your beginning point .

If she collapses when you try and start it, its bad . Lead acid batteries usually don't recover after they go down so far on a alternator failure or deep discharge . They just are never right after that . Batteries only last about 3-4 years now ,they will let you down .

Yup average life for a battery for me down here in "HOT" "HUMID" south florida is 3-5 years tops.! Check your ground for the truck too.
