Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

You need to run some tests when this is actually happening, so you need a spark tester and a fuel pressure tester to see where the problem is at at the time of the failure. You can borrow both of these tools at your local parts store for a deposit too. The most common problems would be a CRANK sensor if you lost spark or a fuel pump if pressure is too low.

Thanks, Ron
