power

2002 ford sport trac 181,000mi on the dash, new engine 58,000mi (still the 4.0 sohc) 2nd owner Spectre air filter 1.5 in wheel spacers Nothing else yet haven’t had for very long wanting to modify it but need to get a tuner first! Any suggestions? What’s good ways to make power on these bad boys...

My 04 lost power the other day when i pushed done on the breake and it completely died. It did start back up. Does anyone have any suggestions about why it may have happened.
