Engine stops intermittently, will some times start back up some times will not. Also, if I use to many accessories at once seems to overload system and results in engine failure and power loss to some functions.

Good afternoon my name is Roy and I will assist.

I would start by checking the fuel pressure. There is a valve on the fuel rail you can use to test it. You can rent a tester at a parts store. You may have a failing fuel pump causing the stalling.

Start there and report back to us with the results.

I am losing power to some electrical components, I can make engine failure by rolling windows down and adjusting seat.

Okay, then start at the battery. Check the voltage with the engine off and then with the engine running. Let me know the results.
