It sounds like the timing chain has jumped. to be sure lets do a compression test. This guide can show you how:

I forgot to mention I did remove the top cover an check the timing it's on point and also I pull to the side switch off remove positive battery pole starts an work okay until the issue arise again. Will still do the compression test. Will keep you updated.
