Squire P Bass randomly gets zero to extremely low output

[DuckWithBoots]

I recently bought my first bass, which is a Squier P Bass, after learning guitar. The problem with the bass is that it will quite often randomly have zero or extremely low output when I plug it in after letting it sit for a while. Only once did it drop to zero while I was playing. I believe the problem lies in the pickups after troubleshooting with different cables and amps, but I'm not 100% sure.

 

So far, the ways I’ve managed to get the bass working again include:

Waiting a bit until the output fixes itself.

Pressing on the pickups until it works.

Flipping it upside down.

Check the solders, one (or more) is certainly dry.

 

It could also be a hot (this is how the "positive" is called) wire touching the ground intermittently.

Another vote for this; there's very little to actually go wrong, and barring something truly bizarre the solder joints or a short would be my suspicion.

Have you tried twiddling the volume knob when it goes quiet?

Could be the output socket. The ones on squiers are never the best, and I have had them fail with the signal intermittently cutting out. Now I always solder in a switchcraft or pure tone before that happens.

Pickups tend to either work or not. There's not usually any middle ground.

 

The first thing to check is the jack socket. Give it a squirt of electrical contact cleaner and then insert/remove a jack plug several times. Similarly rotate each knob fully both ways many times. Those are places where you can get a dodgy contact, especially if the bass hasn't been used for a while 

 

The circuitry is very simple

...and foil backed scratch plates being the only ground...
