I have been experiencing burning pain in stomach accompanied by bloating and heartburn what could this be?

Unsure.: from your symptoms it is impossible to pinpoint a definite cause. A good initial approach would be to try using antacids for a brief period of time, 1 to 2 weeks, to see if this helps. If it does not, or if the symptoms recur, I would recommend that you see your primary care doctor to get a better handle on them and to begin treatment. Be sure to follow the directions on the label. Good luck.
