I'm sure this is probably somthin simple. So any help is appriciated, Car starts fine runs OK only gets 5 psi boost, runs OK for about 10 min, then engine light comes on and barely runs at all. Any help is appriciated, Thanks.

 

You need to check the engine code - that's gonna be your first clue to the problem. Do a search and learn how to check the engine codes - it's pretty easy.
