Just recently timed the engine and put in a new tensioner. Everything was done correctly and the car started immediatly afterwards. The car ran for about 5 minutes then made a loud sucking noise through the intake like it was taking a gasp of air and stalled out. The car started again ran for 3 or 4 more minutes then did the same thing and now it wont start. The engine will crank and fuel pressure is within specifications. Any ideas?
