i just picked my car up from the shop. i spent 300$ on a ingnition switch and a PNP switch to fix my intermiten starting problem. it started right up but wouldn't start after the five minute ride home going no faster then 50 MPH it wouldnt start. when it doesnt start it doesnt even turn over nothing happens. i have tried to wiggle the shiffter but that didnt help. i have also replaced the batterie. The car will start fine when its cold and once it is started it runs fine. If i use it for a short trip it will not start or when its really hot and sunny out. I have been told that i needed the new PNP switch by many people but that wasnt the problem. what is wrong with it.
