i have a 1978 ford ranger f-250 and if it like stalls out or something of that sort the battery goes dead.. and i become stranded.. and i have no idea why it keeps doing this..

 

Welcome to the site..

First thing to check,, would be to 'make sure' the trucks charging system is working.. Most aftermarket parts vendors will check the system 'charge rate' for you at no cost, as well as the battery 'state of charge' (load test).. If the system isn't charging,, or replacing the spent voltage draw, the truck will only run until the needed or system voltage finally falls enough to be able to supply/fire the ignition components ending in a stall.. If the truck cranks over and starts OK after sitting for some hours, or better yet overnight, then, stalls after some driving with a now dead/very low battery, I'd suspect the charging system.. The trucks gauge/light usually doesn't give a good enough indication of a real charging rate, and should be physically checked to at least take the charging system off of the diagnostic list.

If after it stalls,, the truck 'cranks over' fine with a good/hot battery with a 'no start' at all, and then is cranked over until it eventually kills the battery, then it may be another issue..
