Pontiac Repair: pontiac 1995 transport, engine cranks, pontiac transport

Question
i have a 95 pontiac transport 6 cyl. starts and runs fine when cold but when it gets hot,  engine dies. after sitting 10 to 15 minutes it starts right up. when it is off engine cranks but does not start.

Answer
you will prob have to put it on the computer to a live screnn display and see what the raadings are and what is shutting down. when the engine cranks but wont start see if it has fire to the plugs and or fuel injection pulse, it sounds like an electrical component is failing whe n it warms up, need compuert test to see what one also check and see if the exhaust i sflowoing out of it at a satisfacorty rate a clogged cat can do the same thing
