1997 chevy silverado 1500 just stops!!!

Okay so about 2 month ago my truck hit 200,000
miles . Well anyways i was driving on the
interstate.  And it just shut off on my and wheel
locked and every thing . So i pulled over and shut it
off.  Started it back up and it was fine for like 5 min
then it did it again .
Well once i tried to start it and go there was no
power. So we changed the fuel filter and fuel pump
and it started working fine.  Well 2 days ago i was
driving in cruise crontrol and it happened again.
But i was able to start it back up and go home .
My husband drove it yesterday and it drove just
fine . I drove the truck today....
And it just shut off on me !!!
So i pulled over restarted the car and it would
barely go. For a very long time then i restarted it
and it worked perfectly fine.
What could this be i need help!!!!
