Ok so i bought this used ampeg ba300/115 used from musicansfriend just over a month ago. Once before when i was playing it just shut off when i was playing, i thought it just overheated so i turned it off for 15 mins and it was good. But after only playing 10 today it just shuts off. i turn it off then let it sit for 5 mins again. after another 15 mins it shuts off. What should i do? What can be causing this? Thanks because im like spazing out now
current gear:
ld15 amp
fender j bass

Take it to a shop. It could be a number of things, I had this problem with my amp for a while when we practiced in my guitarists kitchen, and at a few gigs.

As it turns out, my amp is just power hungry, and hates to be connected via a power extension, it just needs to be plugged straight in, and it wasn't getting enough power. Was nothing even wrong with my amp.

There's so many things to go wrong with electronics, the best thing you can do is let a professional look at it. It could be something as simple as a loose wire.
