MY TRUCK WONT CRANK WHEN I TRY UNLESS I HOLD THE KEY IN THE ON POSITION FOR AT LEAST 15 SECONDS. I REPLACED THE STARTER RELAY AND IT STILL DOES IT

Today my truck actually shut off while I was driving. When I put it in park and tried again, it started although I had to wait two minutes before putting it in drive otherwise I would cut off.

Check engine light on? Recent repairs? Last plugs/filters? Do you have way to check fuel pressure? Any other running problems?
