I recently got a 60 inch Sony KDF-E60A20 from a friend for around. ... runs for about 1 minutes then goes black(no picture no sounds), then the picture and sound come right back on for another minutes then off for 30 seconds.

sounds like its not getting gas fast enough to keep burning,that happen to me and the gas line was to long of a run for enough gas keep coming. so I up the pipe runs real good the flame keeps burning, so you know you can only go 25 ft in half inch pipe then u lose your flame

1. CRT or LCD?
2. Do you have an image of any kind for that 45 sec.?
When it drops out after 45 sec, do you have any strange behavior as you look at the screen (colors, blinking, lines, squiggles, noises, smells)?
3. When failing, does the power drop out (ON light goes OFF)?
How long do you need to wait until you can turn it ON again?
4. What is the status of your screen saver/power saver? 45 sec seems pretty short but it's still possible.
5. What does the manufacturer's website have to say about this problem? What do other users have to say when you search for your model?

I know these are just more questions but your question is too generic to offer specific comments that might be more useful.

Check the tv "LAMP" LED light indication is it flashing or staying on?Yes,than it is the bulb.

Try this:
1) turn on the TV
2) from the remote control press MENU 2,4,7,0 then ENTER
3) tv will state on screen that it is INITIALIZING
4) when done press the front reset button.
5) should be good to go!

it might be the bag or the sensor inside the machine.

video board is shot, providing u still have sound. must replace.
