I have a PMP5000, used 5 times now. Last gig I started losing output to the point where I had nothing coming out of my speakers, but control room/headphones was fine. Is it possibly a cooling fan and the unit overheated. WTFO

Cease using it immediately and get it serviced. There are failure modes of this that can do serious damage that requires a lot of work to repair.
If the temp sensors shut it down, it will restore if cooled off... If that doesn't happen service is required.
If just one side of the speakers went out I know exactly what has happened as I have repaired three of these all with same problem. If both sides are down and the rest seems to work, that is an uncommon failure
The cooling fan is throttled as needed and runs only when heat sinks get to a certain temp.

You don't say what item of Focusrite equipment you are trying to connect or for what purpose. Most focusrite stuff has jacks with analog outputs for each channel that can be used into the line ins on the mixer and jack/xlr combos that can be used to take a signal to the focusrite box. Then you get the firewire side for the PC and digital outputs as well which will not be of use with your mixer.
Chances are you've blown the output transistors. Speakon connectors cannot short out but jack connectors can and if it was not inserted properly you'll have presented a dead short to your powered mixer. In any event it is really bad idea to connect anything when it's switched on. If you're really lucky replacing the output stage (which will probably be dead short on the transistors) and re-adjusting the bias should sort you out.
Use a two channel INSERT SNAKE. Plug the TRS connector for each channel into the INSERT jack for the mains in the area above the effects unit. Plug the TIP of each channel of the snake into the input of your effects unit and the RING plug into the output of your effects. The snake has ONE TRS connector and TWO TS connectors per channel.
Yes, you can use both the main1 and main2. They are independently driven and please note that they are PSUEDO balanced drives... that is the cold side of the balanced line is NOT driven as a complement, but is merely returned to signal ground by a 120 ohm resistor. This CAN cause hum problems or noise pickup depending on the connected equipment and ground loops. Best to run this into amps/speakers thaat have TRUE balanced inputs and also keep the power source the same for all devices.
Yes, you blew out components associated with the monitor sends. There are several components including an RF bypass to ground and the driver IC, IC8 and a decoupling electrolytic cap. The repair is going to be extensive as it is likely you will have to remove ALL the panel knobs and screws to free up the circuit board for repair. I have worked on several mixers and have three of the PMP5000's myself and dread removing the main board. I am going to suggest something you might consider: Many of the PMP's fail either in their power supply or one of the amps. Due to the repair cost I would consider getting a scrap PMP with this problem and swapping out the panelboard for yours. Often you can get one with blown supply or power amp for around $200 and I suspect a repair shop is going to charge at least that to repair your unit... Then you will have a spare parts bucket as well.
You blew the driver chip for those sends... NEVER plug the outputs of power amps into a mixer period... These chips are surface mounted and you will probably/maybe have to take the main board out of the mixer unless they are on the bottom side... I have several of these mixers and I might be able to uncover the main board of one I have open... Here is the schematic for the PMP5000: http://elektrotanya.com/behringer_europower-p0569_hca2400_sps1000_dpx_pmp-1280s_5000_sch.pdf/download.html
Scroll down to "get manual" and click to download... IGNORE other download links on the page. It looks like you might have blown IC8 on page 5 which is one of the monitor sends. It is a standard NJM4580 chip... a little dual op amp that is SURE to be surface mounted. There is a possibility that capacitor C60 and its mate for MON2 may have been blown so check those. If the board has to come off the front panel... "enjoy" pulling off all the knobs, removing the nuts on the 1/4 inch connectors and possibly the screws from the XLR connector to get the panel separated... Been there, done that...Maybe you will luck out and the part will be mounted on the back of the board... Let me know if you need more help... fredy2 on aol.com
Very strange behavior. Knowing the electronics within the unit, I see no reason that moving the main volume could restore operation. i tend to think that is a coincidence. Possibility the vibration of moving the control caused it to operate again. Do read the tip about PMP mixers I posted on Fixya about the hazard of channel A output if you use Speakon to 1/4 inch cables or adapters. If this happens again, try headphones and see if the signal still comes through them. There is an electronic fuse that can kill output IF the output current gets too high, but for that one you have toturn power off for some time for it to reset. Since you did not turn power off per your posting, that possibility is ruled out. Normally the sliders will NOT fail midstream and would be restored with any slight movement.
When using the trim with mics such as SM58's, etc. the trims often wind up at about 3 o'clock in normal use. You set the trims by pressing the PFL buttons down and setting the level using the led display histogram so that at maximum level of talking/singing the display never goes clear up to clipping.
IF you have feedback, then you have issues of mic location and speaker location. The critical point of feedback is far too critical to set with the trim controls.
Your main speakers should be toward the audience from the mics, not so the mics can "hear" the main speakers.
Monitor speakers are ALWAYS a problem with feedback... performers want more monitor, but depending on the acoustics of a stage, reflection from the back can get into the mics or the mics may not be directional enough... SIngers that choose to hold the mic and wave it around are a soundman's nightmare! They let the mic point toward a monitor and away goes the feedback.
The PMP5000 has a lot of power.
While your at it, PLEASE read my tip on FIXYA about PMP mixers regarding the hazard of using Speakon to 1/4 inch speaker cables... ESSENTIALLY never allow the barrel of channel "A" output 1/4 inch to be grounded as it, instead of the tip of the jack is the HOT lead !!!! This isn't in the user manual... I fix these things and discovered this hazard from the schematics.
It is likely the amps have been blown. Take for repair as further use may cause further damage.
Test the mixer by plugging headphones into the main L and R outputs. Note you will hear only one side of the headphone being these are mono outputs. The level will be low, but will check that the rest of the mixer is working.
ALSO please read my tip on here regarding a hazard of speaker polarity.
Usual problem is the Channel A amplifier has burned and blown the switching transistors. Usually an internal board arc occurs and unless very skilled at board work of clearing the burned area and replacing the components you are better to replace the HCA2400 amplifier module... about $160
