I have a 2000 gmc jimmy that wants to start sometimes and others it wont. When it is running it idles and drives fine untill about 55mph. I did a solid tune up so cap rotor, pcv, airflow sensor. fuel pump seems to be working fine but i lose power and can hear the engine missing at about 55, HELP...

Check it for restriction in the exhaust and test the fuel pressure.
