I think this is a common mistake that the shop says they ran diagnostics to figure out the issue. It gives the impression that they scanned the vehicle like a computer spyware scans its system to look for virus'. Unfortunately this is not the case. When they scan the vehicle they are just checking for codes. If there are no codes then the shop needs to test the systems that would cause this. This requires them to know what would cause this and test that system.
This issue sounds like a fuel issue. So we need to know what the fuel pressure is when this is happening. Here are some guides that will help with this:
Below you will find the process from the manual that helps with testing the fuel system. However, if you let us know what they found that would help. I am interested to see what they found.
