Okay, so a couple days ago two of my speakers went out on my 98 xlt 4 cylinder. Then the wipers stopped, the same day the truck died on me. Borrowed my grandpa's ram 1500 for a day and put a new alternator on it since the battery is 2 months old. If I jump it off it will run and drive fine for about 10-15 minutes then it'll die again. I don't think it's the battery and I put a brand new alternator in today. I don't know what's wrong and I don't want to have to push it out of another interesection. The truck is right under 260,000 miles and I wanna keep her running. Any ideas guys?

 

Buy/get a volt meter and save yourself some money.

Why do you think any of what you described has anything to do with the battery or alternator?

New battery should read 12.5volts or higher, with engine off
With engine running battery voltage should read 13.5volts or higher, but no higher than 15volts.
With engine running turn on head lights and set heater fan to High, battery voltage should stay above 13.5volts

If that's what you get then battery and alternator are fine.
If not then you have blown fuse or bad fusible link

In the engine fuse box, find the Alt Sys Fuse, 30amp, check it
On the outside of this fuse box is a 175amp MEGA Fuse, check it

Does the battery light come on when you turn on the key?
It should, if not check Fuse #15 7.5amp in cab fuse box

1998 Ranger had 4 speakers and you said 2 quit working, all 4 run off the same amplifier so this is not a 12volt battery power issue.

Wipers have their own fuse, have you checked it?
#16 30amp in cab fuse box
