stalling

I have a 98 S-10 that while I'm driving I lose power for a second or two and then my engine kicks back on. That happened 3 or 4 times and now it is doing everytime I drive but now when I stop and start to move it's stalling and not starting... I let it sit for a few minutes and it starts. Then yesterday it stalled and I pushed it off the road and it wouldn't start, I set my E-Brake and tried before I walked away and it started... I released the brake and it stalled, strange? Fuel pump or CPU? I'm not showing any codes and other then that it runs good. Can someone set me in the right direction? Thanks

Make sure that the battery cables are tight.
Loose cables can cause gremilins like that at times
