Most vehicles if you get the car running and unhook the positive battery cable it will stay running that is because it is running off the alternator. if it dies like your talking about I would most definitely say your alternator needs to be replaced. Most likely when you jumped your father in laws pick up there was a bad ground somewhere and your alternator got a surge of electricity and it fried it. Hope this helps.

sound like might have a prooblem with the charging system. if the altenator is not charging the battery while driving then when the battery voltage gets too low (prob around 10volts) then the computers will shut down, then when jump started it gets some power back, and when the battery is charged will all work fine for a while.
does your model have the voltage gauge in the dash? should be over 12 volts when engine running, 14volts is a good charge rate. and should stay up above 12 all the time, with lights on air condon etc...

Sounds like the Altenator has died, you have been running on the battery alone. If you give the battery a good charge, you can go quite a while as long as you turn off as many accesories as possible. good luck

Truck starts and then does'nt start

When you say doesn't start do you mean you have to jump start? If so it is something to do with charging system. If alt is charging fine, then you probably have a bad cell in your battery which would cause this type of problem. Sometimes it works sometimes it won't. Eventually it won't anymore without a jump.

Electrical Problems

Al, this truck has a regulator locted inside the altenator, it also has a relay located in the power distribution box under the hood, see your owners manual for exact location, to verify an no charging problem, start the truck and measure the voltage at the battery, it should read 13.5v-14.5v, if not then the altenator is not working, most common problem is regulator failure requiring altenator replacement, hope this helps, let me know
