Sometimes it will not start but only if do not get the audible dings it will not start, but all the electronics come on normally. I can cycle the key to off then back on and will normally start. While driving under forty five mph (never seen happen faster) the engine will randomly turn off. When that happens the low oil pressure, trailer brake module fault, and service advancetrac pops up. Can put it back in neutral and will not start again until I turn key off then will start back and can continue driving. Cannot recreate it just seems to be random and more so when about to start accelerating again. Before spend a fortune at a dealership figured would see if anyone has a idea or had the same problem. It does not give a code either which makes it very hard to figure out. Thanks in advance.

This sounds like you have a crankshaft angle sensor that is failing or a dirty throttle body causing the issue. These guides will help us find out.
