It could be dirty interupt contacts on the jack you are plugging into. Spray some conct cleaner from the back side and plug and unplug a few times to see if that clears it up. Also spraying the controls and switches- make sure you get the spray stream into the switch or potentiometer to get on the contacts to disolve grime.
Other potential sources are poorly soldered connections on the amp chassis- litterally anywhere. Reflowing all solder connections would likely remedy the problem.
Also make sure the nuts that retain the jacks to the amp chassis are snug and will not move.

You might have a ground problem. Does it do it in different outlets or when you take it to someone else's house? One easy solution to ground problems can be running a three prong to two prong adapter on the power cable. Give that a try and see if it helps.

se3veral things have to be ruled out, start with the cord that your using to your amp, is it good? next is the volume on both the guitar and amp also good, the last thing that should be wrong is the pickup itself unless a wire is broken off of it, you can usally check this from somewhere on the back of the guitar, if all the wires are good, check the two volume controls and on the back of the amp check the wires going to the speaker.

Ah yes, the Fender Hot Rod Deluxe. I have seen more of these in my shop than any other amplifier!! I have even sent recomendations for design changes to Fender about this amplifier.
Sadly, your amp tech may be correct: while the amp is within working specs, you can still have an issue with a bad socket. The cheapest thing to try is to replace the preamp tube(s) you think may be causing the problem. If the problem persists, it may need to be serviced on this issue (by a different 'certified Fender tech'). In defense of the last tech you had work on this amp, these amplifiers have a brittle design and do not gig or travel well (there are a minority of these amps made that do perform). Fender tried to do too much for the price on this model: best advice is to fix it, sell it and get your tone with a more stable model made by Fender (like the new vintage re-issues). Fender, like Marshall, has for years been having problems when they get too far from thier 'working reciepe' of what made them great companies.
You likely have a socket that needs re-tensioned, or a preamp tube not behaving. If it is not these, then a tech had to dive in the house of cards that is this circuit. Sorry for the bad news on this, but it is the truth. I only take on Hot Rods that 'appear' to be fixable. I am a development engineer, build amps from scratch and fix them for the local music shops, and my success rate is a dismal 60%-ish percent on these...
Thanks,-mike

There is a protection thermistor in the circuit to keep it from over-heating, this is why it works again when it cools. Check and make sure you are not covering any ventilation holes, or if the unit has a fan, make sure it is working.

No, when you plug into the power amp in that disconnects the feed-through of the preamp.
