I've had this problem.
There's a strong chance that the wiring harness for the fuel injectors is failing, causing one bank of injectors to be inoperative.
Sometimes a 'jiggle test'of the harness will tell a story. Or use a 'noid light' to test the injectors and see if they're all working.
You can buy a new harness of make up your own
